SOLD - 1981 Piper PA34-220T (Seneca III) - SOLD

The Piper Seneca III is a very desirable model due to the factory 220 hp engines and the gross weight increase that came with them.  There are quite a few Seneca II's with the 220 hp upgrade, but the anemic useful load leaves most buyers looking toward the Seneca III or newer.

N8434M is known-ice equipped with recent refurbishment of nearly the entire de-ice system, including: all new wing and tail boots, fresh overhaul of windshield hot-plate, fresh overhaul of three pneumatic valves, new prop de-ice timer, new boot de-ice timer, and new left prop de-icers.  Fuel systems left and right engine were overhauled in 2010.

This aircraft is available for viewing in Longmont Colorado on appointment.  All specifications are believed to be correct but are subject to verification by buyer.
