Boeing 737 MAX flight control system, a key factor in Lion Air crash

Mechanical and design problems with a Boeing 737 MAX flight control system were key factors in the crash of a Lion Air jet last year, Indonesian investigators told victims’ families in a briefing on their findings Wednesday.

But some grieving relatives expressed anger that investigators were not planning to blame the US airplane maker or budget carrier for the disaster in their final crash report expected Friday.

“We’re not satisfied with the explanation from investigators, but we have no choice but to accept it,” Epi Syamsul Qomar, who lost his son, told reporters after a closed-door meeting with investigators in Jakarta.
