The configuration of the Slats (and flaps) will be a basic part of the initial investigation to verify. The system is well decribed in the MD-80 LAMM Section 27-85-00 page 101-103, including the auto slat behavior and warning systems.
- The Slat position is recorded to DFDR/QAR via the DFDAU
- The cables may have witness marks to indicate position when tensile loads may cause separation of the cable
- The actuator will indicate the position of the Slat drive drum (27-81-1), as will the autoslat actuator MI 76/77 etc. As well, the Flap/Slat handle position will be identifiable
.
quote reports unquote of possible lateral instability will certainly ensure some investigation is conducted in this area by competent investigating authorities.
As to CAWS: the 28v DC -L CB would need to be tripped, B1-832,
AND the 28V DC-R CB B1-851 would need to be tripped for the crew to
NOT get a warning of the CAWS being degraded/failed. (LAMM 31-51-00)
CVR will be interesting.
