Plane Parts Company was founded by the owner of a 1971 Piper Cherokee PA28-180 aircraft who is both an engineer and a pilot. Of course, like most Piper Cherokees, the interior of his PA28-180 was fairly well worn out and it needed a complete refurbishing. What quickly became evident was the complete lack of replacement interior plastic parts. What few parts he did find were outrageously expensive and would take weeks to get. We are sure that you too have run into the same experience. One of the things we found hard to believe was the high price that Piper Aircraft was charging for the smallest items. 20 years ago, a fresh air vent cup from Piper was $45 and the retaining flange was $38! Today, we offer the same parts for around $10 each.
