Accident Number: GAA19CA528
Date & Time: 09/07/2019, 1600 PDT
Registration: N16XC
Aircraft: SIAI-MARCHETTI SM 1019
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 2 Minor
Flight Conducted Under: Part 91: General Aviation - Personal
The pilot of the float-equipped airplane reported that, while taking off from a lake, the airplane accelerated, became airborne, and about 40 ft above the water, he retracted the flaps. The airplane pitched down and the left wing dropped. He attempted to correct to no avail and the airplane impacted the water.
The pilot reported that he believed P factor caused the left roll because the airplane was aerodynamically stalling and would not correct, despite his attempts.
The pilot reported that he had accrued 5 hours in the airplane make and model, 2 hours of which occurred in the preceding 30 days.
The airplane sustained substantial damage to the fuselage, empennage and both wings.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The pilot reported that, it was a very windy, gusty day, and the wind varied in direction. An airport's automated weather observation station, located 15 miles west, reported that, about the time of the accident, the wind was from 300° at 14 knots, gusting to 20 knots. The airplane was departing to the south.

A careful inspection of the photo will reveal that the tail is missing. No one should attempt to take off in a seaplane with the tail missing.
ReplyDeleteThe tail is actually the only part that isn’t missing - the photos show the front, which fell off.
DeletePull the flaps at 40 feet?
ReplyDeleteTurbine engine aircraft. Different power delivery than piston. Retracting flaps to early is result. This was a cool plane but there is a transition unless pilot flew turbines on floats with rr250 power. Only other similar plane would be a turbine Maul on floats.
