The Flight Safety Foundation (FSF) says it strongly supports the use of deployable flight data recorders or triggered flight data transmission capabilities in addition to the standard cockpit voice recorder and flight data recorder already installed on transport aircraft. The FSF believes a deployable flight data recorder should also include an emergency locator transmitter. The International Civil Aviation Organization is considering this option in a proposed amendment to Annex 6.17–Emergency location locator transmitter.
The UK Air Accidents Investigation Branch (AAIB) investigation into the fire on board a Boeing 787 operated by Ethiopian Airlines at London Heathrow Airport on July 12, 2013, discovered improper wiring of the lithium metal battery that powered the aircraft’s Honeywell 406AFN fixed emergency locator transmitter (ELT). According to an AAIB special bulletin published last week, the investigation concluded that the battery had been incorrectly wired to the ELT during the manufacturing process.
Triggered by the loss of an Air France Airbus A330 in June 2009 in the Atlantic and compounded by the loss of a Malaysian Airlines Boeing 777 in the Indian Ocean in March, representatives of ICAO member states and of the aviation industry agreed on a set of near-term priority actions and a framework for medium- and long-term objectives, at a special meeting on global aircraft tracking at ICAO in Montreal on May 14.
The Air Line Pilots Association said in an April 4 statement that it “is unacceptable that the location of the aircraft [MH370] is unknown.
The prolonged search for the Boeing 777-200 operated as Malaysia Airlines Flight MH370 brought attention to onboard data transmission systems that report an aircraft’s position and other information in real time. Such a system could help track an aircraft that disappears from radar coverage.
The FAA issued an airworthiness directive–2013-18-09–on September 18 affecting some Honeywell ASCa emergency locator transmitters (ELTs) installed on transport-category aircraft.
The U.S. Federal Aviation Administration said on Friday it plans to order inspections of the wiring associated with the emergency locator transmitters (ELTs) on Boeing 787s following a recommendation from the UK’s Air Accidents Investigation Branch that operators disable the airplanes’ Honeywell-made systems. An Advisory Directive scheduled for publication today would require inspection for proper wire routing and damaged or pinched wires, the statement said. Operators would also need to inspect the transmitter’s battery compartment for condensation or overheating.
The July 12 fire aboard an Ethiopian Airlines Boeing 787 at London Heathrow Airport (ELHR) has prompted the UK Air Accidents Investigation Branch (AAIB) to recommend operators turn off Honeywell’s Rescu 406 AFN emergency locator transmitters (ELTs) aboard the Dreamliner until appropriate airworthiness actions can be completed.
The UK Air Accidents Investigation Branch recommended Thursday that operators of Boeing 787s disable the airplanes’ Honeywell-made emergency locator transmitter following last Friday’s fire aboard a parked Ethiopian Airlines Dreamliner at London Heathrow Airport.
AOPA “vigorously opposes” the U.S. Federal Communication Commission’s plan to prohibit the future use of emergency locator transmitters (ELTs) that use a 121.5-MHz signal. The proposal will have a negative effect on aviation safety, according to AOPA, and the association told the FCC it should immediately abandon its proposed rule changes and defer to the FAA on matters of aviation safety. According to AOPA, there are more than 200,000 general aviation aircraft still carrying 121.5-MHz ELTs.
