I was wondering if anyone may help a non-pilot (and a non-engineer - sorry!) with a question regarding the Piper Aztec. If you were to lose the starboard engine, what subsequent hydraulic power would you lose in the aircraft? What about the port engine? Put more simply - which engines drives what hydarulically-powered flight surfaces and systems? What else may be lost if either one of these engines were lost?
Also, what (if anything) could cause the radio to lose power or not be able to transmit during the flight? Thanks very much...

Its been a long time since I have flown an Aztec, though I think my memory is alright. The left engine has the hydraulic pump. ( I believe there was an option to have one installed on the right engine also in later models) You lose gear and flaps without the engine-driven pump. There is a hand pump on the center console which may be used for both gear and flaps. (seperately of course) There is also a blow-down bottle which uses CO2 as a last resort as it contaminates the hydraulic system.

You're quite right, S&S: even if both selectors are moved at the same time, the gear activates first. There is also a priority valve in the undercarriage system that ensures the (forward extending) NLG comes down before the MLG as it has the airflow to contend with.
Flyingbeagle - there aren't any hydraulically powered/assisted flying controls on an Aztec (or any other light piston-engined commercial aircraft that I know of) and the separate brake system works purely by foot pressure. A number of things could cause the radios to fail, from a popped circuit breaker to a broken aerial.
