Search and Debris Examination Update
MH370 - Search and debris examination update
Safety Investigation Report (2018) Appendix 2.6C
Damage Analysis of Significant Debris
Damage examination on the recovered part of the right outboard flap (Item 19), together with the damage found on the right flaperon (Item 1) indicates that the right outboard flap was most likely in the retracted position and the right flaperon was probably at, or close to, the neutral position, at the time they separated from the wing.
...
With the flap in the retracted position, alignment of the flap and flaperon rear spar lines, along with the close proximity of the two parts, indicated a probable relationship between two areas of damage around the rear spars of the parts. This was consistent with contact between the two parts during the aircraft breakup sequence, indicating that the flaperon was probably aligned with the flap, at or close to the neutral (faired) position. Refer to ATSB’s report on the Outboard Flap Failure Analysis (Appendix 2.6C) for further details.
