BUT----135.169 DOES apply to recip engines, read my previous post.

135.399 deals with aircraft certified under 135.169--whether they be piston OR turbine, because .169 deals with both. Read the very first sentence in 135.169 (b) and recips are the first engines to be mentioned.

.169 airplanes have 10 or more passenger seats, not counting pilot seats.

Therefore, a 5 passenger seat Baron does not really fit under 135.169, and therefore does not fit under 135.399.



I have underlined where I am talking about below in my next post.
