F.Y.I. APRA Rules Enforcement At Whittier
Hi Guy's and Gal's;
I've been watching this thread and I agree with about everything thats said.
In the old day's when Rossi's were the Q-500/40 engine of choice as well Webra Q-'s. AMA had no problem with us welding the muffler shroud, as this was a preventive measure not a modification. Idle stop screws on the Rossi's were notorious for breaking the nipple off, so and after market Royal Chrome Idle stop screw was found to replace the standard black that came with the Rossi. These also were found not to be a modification, just preventive maintenance.
Rule for modification as some have ref: A good engine man or woman/CD/Inspector, if need be can tell pretty quick by harmonic's, Rpm, calipers for measuring carb intake etc. on whether the engine was modified or just repaired.
I see no reason to condemn someone for preventing a piece of metal from flying off his aircraft at 100+ Mph.
