A friend just contacted me about a 7AC that has been modified to 7ECA with O-200. Anyone heard of this?
7AC to 7ECA
- Thread starter Ron86654
- Start date
Champs can be modified with all sorts of different engines but they are limited in max gross weight and the O-200/300 are heavy engines for the HP they're producing so your friend might want to investigate the empty weight to see what the useful load is.
From the article,"Coleman Wagner has two STC’s for installing either a Lycoming O-235 engine or
a Continental O-200 engine in Chiefs and Champs.
1. STC SA3-372 covers the engine installation in 7AC and 7AC Conv model
aircraft.
2. STC SA57RM covers the engine installation in 11AC, S11AC, 11BC,
S11BC, 11CC, and S11CC model aircraft.
Like the Lasher STC, the Wagner STC’s have specific nameplate stamping
requirements, and like the Lasher STC and conversion letters, the requirements
are in conflict with the FAA Order 8136."
