EADS Socata TBM 700C1, N700GY
The pilot of a TBM 700 landed with three green lights and a red light showing on the landing gear control and indication panel; the nose gear subsequently collapsed during the rollout. He had interpreted the three greens as indicating that the landing gear was locked down, however the red light signifies that the gear is unlocked and takes precedence over the three greens. Although the correct procedure required the landing gear to be operated manually using the hand pump, it was dependent on the pilot recognising that a red warning light signifies that the landing gear is unlocked, even if three greens are displayed concurrently. The lack of clarity in the TBM 700 Pilot’s Operating Handbook (POH) regarding the significance of the red warning light was considered to be a causal factor in this accident. One Safety Recommendation is made to improve the clarity of the Emergency Procedures in the TBM 700 POH.
