Location: Willow, AK
Accident Number: GAA18CA087A
Date & Time: 12/18/2017, 1120 AKS
Registration: N61SR
Aircraft: MAULE MX7
Aircraft Damage: Substantial
Defining Event: Ground collision
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal
Analysis
The pilot of the Piper airplane reported that, while taxiing from the runway to his tie-down space, he was taxiing "into the sun". He added that, before he could react, he struck the tail of a Maule airplane, which was stopped on the taxiway.
The pilot of the Maule airplane reported to the Federal Aviation Administration inspector that he was planning to depart and had stopped on the taxiway to put on his seat belt, when his airplane was struck from behind.
The Piper sustained substantial damage to the right wing lift strut; the Maule sustained substantial damage to the empennage.
The Piper and Maule pilots reported that there were no preaccident mechanical failures or malfunctions with the airplanes that would have precluded normal operation.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The other pilot's failure to see and avoid another airplane parked on the taxiway while taxiing in sun glare conditions.
Findings
Personnel issues
Monitoring other aircraft - Pilot of other aircraft (Cause)
Environmental issues
Aircraft - Effect on operation (Cause)
