FAA PROPOSES

FAA Proposes $51,651 Civil Penalty Against All American Aviation Services The Department of Transportation's Federal Aviation Administration (FAA) is proposing a civil penalty of $51,651 against All American Aviation Services, LLC (All American) of Tomball, Texas for allegedly violating FAA drug and alcohol testing regulations.   The FAA alleges that All American allowed eight employees to continue working in safety sensitive positions for more than 30 days after they were hired, even though the company had not obtained drug and alcohol testing records from their previous employers. The FAA also alleges that All American failed to comply with procedures for follow-up tests on two of these employees, who tested positive for marijuana use prior to being hired by All American. The FAA alleges that one of the employees who tested positive was not included in All American's random testing pool for nine months. In addition, the FAA alleges that All American did not receive a verified negative return-to-duty drug test result for the other employee who tested positive. All American is a charter and cargo carrier that primarily serves the offshore oil and gas industry. The FAA discovered the alleged violations during a March 2013 inspection of All American's antidrug and alcohol misuse prevention program. The alleged violations occurred between February 2012 and the time of the FAA's inspection. All American Services has 30 days from the receipt of the FAA's enforcement letter to respond to the agency.

AVIÓN DESAPARECIDO DURANTE MEDIO SIGLO

Sucedió el 2 de agosto de 1947, el avro 691 de British South American Airways, en vuelo CS-59 procedente de Buenos Aires con destino al aeropuerto Los Cerrillos de Santiago de Chile, anunció a la torre de control que aterrizaría en cuatro minutos, sin embargo ese aterrizaje no se produjo. La aeronave desapareció  con seis pasajeros y cinco tripulantes.

Circularon infinidad de teorías, incluidas las extraterrestres, ya que basados en el último mensaje radial se escuchó una palabra indescifrable en la terminología aeronáutica. El mensaje decía: "ETA (tiempo estimado de llegada) Santiago 17:45 hrs STENDEC".

Fue en enero de 2000 cuando unos alpinistas encontraros restos humanos y fragmentos de una aeronave en el volcán Tupungato, en Argentina, a unos 80 kilómetros del aeropuerto de Santiago.

El estudio de los restos del avión arrojó que los motores de éste no fallaron y que tampoco hubo una explosión, sino que solamente se impactó contra la montaña.

La conclusión fue que una corriente de viento alcanzó una velocidad muy alta que hizo que el avión cambiara de rumbo y esto sumado a la velocidad y poca visibilidad, hizo que el avión se estrellara contra las montañas.

FAA

Review Team Finds Boeing 787 Design Safe Recommendations Address Manufacturing Risk Mitigation The Department of Transportation's Federal Aviation Administration (FAA) today released the findings of a review team formed in January 2013 to review the Boeing 787's design, manufacture and assembly processes. The joint team of FAA and Boeing technical experts found that the aircraft was soundly designed, met its intended safety level, and that the manufacturer and the FAA had effective processes in place to identify and correct issues that emerged before and after certification. The team made seven recommendations for further improvements in Boeing processes and FAA oversight. FAA Administrator Michael P. Huerta asked the team to review the 787's critical systems on January 11, 2013, after a lithium battery fire on a 787 in Boston. The FAA members were engineers and other technical experts who were not closely involved in the original 787 certification process. As one indicator of the B787's intended safety level, the team compared service reliability data from the time the aircraft first started service with similar data from other previous Boeing airplane models. They determined that the B787's reliability performance in the first 16 months of service was comparable to the reliability of other new Boeing models over the same time period, including the B777. "After the first Boeing 787 battery incident last year, I called for a comprehensive review of the entire design, manufacture and assembly process for the aircraft as well as a critical look at our own oversight," said FAA Administrator Michael P. Huerta. "The review team identified some problems with the manufacturing process and the way we oversee it, and we are moving quickly to address those problems." Team members traveled to manufacturing facilities in the U.S. and abroad and used in-service data and safety risk management principles to conduct in-depth reviews of the B787's critical systems. They chose specific components to examine more thoroughly, including the aircraft's Variable Frequency Starter Generators, Electrical Power Panels, Fuel Line Couplings and Aft Fuselage Sections. The team identified issues in the manufacturing and supplier quality areas and made four recommendations to Boeing to address those issues. The team made parallel recommendations to the FAA for improved, risk-based FAA oversight to account for new business models. The FAA already is addressing the team's three FAA recommendations by revising internal policies and procedures for manufacturing oversight. The team recommended that Boeing should: continue to implement and mature gated design and production processes; ensure suppliers are fully aware of their responsibilities; establish a way to ensure suppliers identify realistic program risks; and require its suppliers to follow industry standards for personnel performing Boeing-required inspections. The team recommended that the FAA should: revise its order on certificate management of manufacturers to recognize new aircraft manufacturing business models; revise its order on production approval procedures to more fully address complex, large-scale manufacturers with extended supply chains; and revise other orders to ensure engineering conformity inspections for all projects are based on risk. Based on the team's recommendations, the FAA is revising its policies, orders and procedures: to use risk tools to ensure manufacturing surveillance is conducted at the highest risk facilities; to assess risks related to emerging technologies, complex manufacturing processes and supply chain management; and to make engineering conformity determinations using standardized, risk-based criteria. As a result of those changes, FAA manufacturing inspectors will expand their review of production and quality data for critical suppliers, including those located outside the United States. Through a Global Manufacturing Team the FAA chartered in 2011, the FAA is allocating resources to the areas of greatest risk at the point of manufacture to maintain appropriate FAA oversight. The FAA also is working on a rule to strengthen the supplier reporting process for quality issues at all tiers of the supply chain.

OTRO MISTERIO : EL BOEING 707 DE VARIG

Como en Malasia, el misterio del Boeing 707 de la compañía VARIG en vuelo 967 destino Rio de Janeiro que se perdió media hora después de haber despegado del aeropuerto de Narita (Japón) en la noche del 30 de enero de 1979. Era un carguero que transportaba 20 toneladas de recámbios informáticos y 53 obras del pintor japonés Manabu Mate, valoradas entonces en 1.200.000 dólares y se cree que cayó en algún lugar del Océano Pacífico. Lo cierto es que hasta ahora no se han encontrado los cuerpos de los seis tripulantes ni tampoco los restos de la aeronave.

El avión de Varig había despegado de Narita a las 20:30, y su último contacto con el controlador de tráfico aéreo fue a las 20:55. Tenía previsto hacer un nuevo contacto a las 21:23 pero eso no ocurrió, lo que despertó la sospecha de que algo extraño había ocurrido.

El controlador de tráfico aéreo intentó la comunicación pero nadie respondió. La ruta indicaba que la aeronave debía cruzar por Honolulu (Hawai) y Anchoranhe (Alaska).

A la mañana siguiente comenzaron las búsquedas en Japón: aviones estadounidenses y barcos nipones inspeccionaron la zona donde probablemente el avión había caído. Una semana más tarde desistieron.

Una de las hipótesis sobre lo que ocurrió indica que el avión pudo haberse despresurizado durante el vuelo, lo que llevó a que la tripulación perdiese la conciencia. Según esa versión la aeronave voló en piloto automático hasta que se le acabó el combustible, tras lo cual cayó al mar.

Otras teorías sugieren que el avión fue derribado por haber entrado, sin autorización, en el espacio aéreo de la entonces Unión Soviética.

¿ QUE OCURRIÓ EN EL MH-370 DE MALAYSIA AIRLINES ?

El Boeing 777-200 de Malaysa Airlines, matricula 9M-MR0, despegó del aeropuerto de Kuala Lumpur (Malasia) con destino a Pekin (China) con 227 pasajeros (154 chinos, 38 malasios, 18 indonesios, australianos e indios, 4 franceses, 3 estadounidenses, 2 neozelandeses, 2 ucranianos, 2 canadienses, 1 ruso, 1 italiano, 1 holandés, 1 austriaco y 12 tripulantes. Alcanzó el nivel FL350 y a los 40 minutos de vuelo, aproximadamente a 90 nm al noreste de Kota Bharu (Malasia), en el Golfo de Tailandia estaba en contacto con el Centro de Control de Subang, casi a punto de entrar en el Centro de Control de Tráfico Aéreo vietnamita.

En este momento la radio y el radar perdieron  el contacto, eran las 02:40 hora local, 17:22 Z del pasado 7 de marzo, y la aeronave desapareció. La última posición del radar era N6.92 E103.58. No hubo ninguna señal de socorro.

La aeronave estaba pilotada por un experimentado piloto de 53 años de edad y 18.365 horas de vuelo y un primer oficial de 27 años y 2.763 horas de vuelo.

BREVE HISTORIAL DE BOEING 9M-MR0

La aeronave desaparecida tenia el número de serie 28420 LN:404 y había realizado su primer vuelo el 14 de mayo de 2002. En 2012 realizó 100 vuelos, 300 en 2013 y 50 en 2014. El 9 de agosto de 2012, en el aeropuerto chino de Shanghai Pudong, colisionó en tierra a las 16:40:00 con un Airbus A340-800 de China Easten Airlines. El ala derecha del Boeing quedó dañada.

POSIBLES CAUSAS DE LA DESAPARICIÓN

Se están barajando diversas hipótesis; una sería la posibilidad de un atentado y otra podría ser que la aeronave, como consecuencia de la colisión antes citada, sufriera un serio daño estructural que provocara su destrucción.

CAOS E INSEGURIDAD AÉREA EN LA REPÚBLICA DOMINICANA DENUNCIAN LOS CONTROLADORES AÉREOS 

 Los servicios de navegación aérea dominicanos ponen de manifiesto deficiencias relacionadas con la seguridad que podrían eventualmente producir una tragedia.

La Federación Internacional de Asociaciones de Controladores de Tránsito Aéreo ((IFALCA) que aglutina a 50.000 controladores de tránsito aéreo en 130 países, han dado la voz de alerta a la Asociación de Pilotos de Líneas Aéreas (IFALPA) y a la Organización de la Aviación Civil Internacional (OACI).

En una carta al director del Instituto Dominicano de Aviación Civil se establece que las deficiencias existentes le fueron comunicadas en al menos 12 documentos remitidos en 2013 por la Asociación Dominicana de Controladores de Tránsito Aéreo, "sin recibir respuesta ni una sola vez".

FACTORES DE INSEGURIDAD 

Entre los casos de inseguridad denunciados citan "la falta total de comunicaciones de Punta Cana", donde aseguran que los radioayudas para la navegación estrán fuera de servicio, lo cual "fuerza a los pilotos a completar el aterrizaje visualmente". Agregan también que el DME (equipo medidor de distancia) del aeropuerto de El Caley, en Samaná, está fuera de servicio.

United Airlines Opens New Widebody Hangar at Newark Liberty

Hangar expands airline's maintenance capability for widebody aircraft by 33 percent at airport

Just weeks after opening its new Global Services reception lobby at Newark Liberty International Airport, United Airlines today unveiled its latest investment in the New York area's largest hub airport – a new widebody aircraft maintenance hangar.

United invested $35 million to construct the facility, which will help support the airline's widebody aircraft, including the Boeing 787 Dreamliner and the Airbus A350-XWB, which United will begin flying in 2018. The hangar also expands United's maintenance capability for widebodies by 33 percent at Newark Liberty.

"This state-of-the-art hangar underscores United's commitment to the city of Newark, the state of New Jersey and the region," said Ken Burtt, United's senior vice president of technical operations. "The facility will be an asset to our operation, helping us improve the reliability of our aircraft, maintain the highest levels of safety, and provide a superior workplace for our employees."

United has more than 13,000 employees in the New York metropolitan area, 700 of whom are dedicated to technical operations and maintenance at Newark Liberty. Construction of the 90,000-square-foot hangar also had a significant economic impact on the region, as more than 600 local workers helped build the facility.

"United Airlines' investment of nearly $35 million in its new 21st century hangar at Newark Liberty International Airport is further evidence of the carrier's longstanding commitment to New Jersey,'' said Port Authority Deputy Executive Director Deb Gramiccioni. "The Port Authority is especially pleased this widebody aircraft hangar is designed to serve larger aircraft like the Boeing 787 Dreamliner, one of the newer generation of planes for our passengers."

In November 2013, United also completed construction of a 125,000-square-foot maintenance hangar at Washington Dulles International Airport. Together with this new hangar at Newark, United has significantly increased its maintenance capabilities on the East Coast.

United in New York / New Jersey

United is the New York area's largest airline, offering more flights and more seats from the region to more destinations around the world than any other carrier. The airline offers nearly 400 flights each day from Newark Liberty to more than 150 destinations in North and South America, Europe, the Middle East and Asia – as well as service from New York LaGuardia and from New York Kennedy to top business centers.
