Lion Air crash: Boe­ing and FAA to is­sue ad­vice to air­lines on 737 Max jets – re­port

The Guardian Australia - - World News - Guardian staff and agen­cies

Boe­ing is plan­ning to write to air­lines us­ing its 737 MAX jet about how to deal with er­ro­neous cock­pit read­ings that could cause the air­liner to dive, ac­cord­ing to re­ports.

The ad­vice is based on pre­lim­i­nary in­for­ma­tion gath­ered in the in­ves­ti­ga­tion of a Lion Air flight that crashed in Indonesia last week killing all 189 on

board, a per­son fa­mil­iar with the mat­ter told Reuters.

The Wall Street Jour­nal re­ported that US avi­a­tion reg­u­la­tors also in­tended to is­sue safety warn­ings about po­ten­tially sus­pect flight-con­trol soft­ware. The ad­vice from the Fed­eral Avi­a­tion Au­thor­ity would be bind­ing on all US car­ri­ers fly­ing Boe­ing 737 Max 8 ver­sions.

Ex­perts say the Boe­ing no­tice could be about the “an­gle of at­tack”, which is the an­gle of the wing rel­a­tive to on­com­ing air stream, a mea­sure that in­di­cates if a plane is likely to stall.

In­done­sian ac­ci­dent in­ves­ti­ga­tors said on Mon­day that an air­speed in­di­ca­tor on the crashed jet was dam­aged for its last four flights, but US au­thor­i­ties re­sponded cau­tiously to sug­ges­tions of fleet-wide checks.

The news was first re­ported by Bloomberg re­ported on Tues­day. It said the bul­letin to air­lines would alert pi­lots to fol­low ex­ist­ing pro­ce­dures to ad­dress the is­sue. Boe­ing de­clined to com­ment.

Air­lines us­ing the 737 MAX in­clude the Sin­ga­pore Air­lines off­shoot SilkAir, Garuda Indonesia and Canada’s WestJet, but none had re­ceived a bul­letin from Boe­ing.
