EASA To Mandate Swaps Of Faulty EFB Component

Directive would give operators 12 months to replace USB receptacles.

The European Aviation Safety Agency (EASA) plans to mandate swaps of a Fokker Services-supplied electronic flight bag (EFB) component linked to several cockpit smoke and fume events.

In a draft airworthiness directive (AD) published Sept. 27, EASA proposes giving operators 12 months to swap universal serial bus (USB) receptacles made by Lone Star Aviation Corp. or Fokker and installed in more than a dozen types of aircraft. The USB components came as part of a Fokker Services supplemental type certificate (STC) installation or a minor modification, EASA explained.

"Several occurrences on various airplanes have been reported of smoke and fumes in the cockpit, due to overheating" of the receptacle, EASA said. "Investigation results revealed that each of these events was caused by a short-circuit in the EFB charging cable."

Fokker Services issued service bulletins this summer for the affected models, recommending installation of modified receptacles.

Affected aircraft types include Airbus A320 family, A330 and A340; ATR42 and 72; Boeing 737, 757, 767, and 777, Bombardier CRJs and Dash 8s, and Fokker F27s, F28, F70s, and F100s. The 737 and Dash 8 installations were done under STCs, while the others were via minor modifications, EASA said.

The draft AD's public-comment period runs through Oct. 25.
