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.

The UK’s Air Accidents Investigation Branch reported last week that the cause of the March 16 accident in which an Airbus Helicopters EC135T2i crashed into a busy pub in Glasgow is still unknown. “[The] investigation to date has not identified any technical malfunction that might account for the accident.
The continuing investigation into the crash of an Airbus Helicopters EC135T2i in Glasgow, Scotland, on November 29 last year has yet to explain why pumps that would have transferred fuel from the aircraft’s main tanks to its supply tanks were not activated. An interim report by the UK’s Air Accidents Investigation Branch (AAIB) concluded that both of the aircraft’s fuel transfer pumps were found in the “off” position after the fatal crash.
Bond Air Services has grounded its EC135 helicopter fleet in the wake of a November 29 accident in which one of the aircraft it operates for local police crashed into a pub in Glasgow, Scotland, killing nine people and injuring 32 others.
The UK’s Air Accidents Investigation Branch (AAIB) has released a further update on its investigation into the August 23 ditching of a Eurocopter AS332L2 Super Puma off the Shetlands islands. The latest document reveals that during the approach the pilot’s attention was drawn several times to a too-low-height warning.
The fatal crash of a CHC Scotia-operated Eurocopter AS332L2 Super Puma on August 23 off the Shetland Islands in the UK has created an outcry among passengers and is puzzling experts. Investigators have found no evidence of technical failure so far, nor have they hinted at human factors. Meanwhile, a pilot based in the North Sea noted that the helicopter seriously deviated from the expected course, two nautical miles from its destination, Sumburgh Airport.
The UK Air Accidents Investigation Branch (AAIB) recovered the cockpit voice/flight data recorder today from the Eurocopter Super Puma that ditched last Friday, killing four.
All Nippon Airways and United Airlines have found minor wiring damage on a total of three Honeywell-made emergency locator transmitters for Boeing 787s and have returned them to their manufacturer for inspection, the airlines revealed last week. The discoveries arose during inspections of the systems recommended by the UK’s Air Accidents Investigation Branch and mandated on Thursday by the U.S.
The U.S. Federal Aviation Administration on Thursday issued an airworthiness directive (AD) calling for either the removal or inspection of the Honeywell fixed emergency locator transmitter (ELT) in Boeing 787s.
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.
