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.
