Fuselage tube inspection (SB 36)
Mandatory for all serial numbers. A broken tube was found in the empennage during an annual inspection. Inspect those tubes within 40 hours or at the next annual, whichever comes first, then at every annual. Only FAA certified mechanics or repair stations may do it. Ask for the logbook entry.
Exhaust muffler inspection (SB 35)
Mandatory for all A-1C-180 serial numbers. At 250 hours, within 40 hours or at the next annual, then every 100 hours, remove and inspect the muffler (P/N 35650-002), baffles and heat exchange system. Cracks at the tailpipe base can be repaired. Cracks on ridges or in valleys require a new muffler.
Doors-open flight and altimeters
Service Letter 4 lets A-1C-180 aircraft with the larger-door fuselage (S/N 3036, 3048, 3050 and up) fly with doors open up to VNE. The owner removes the prohibiting placard and AFMS #SII4000DE-A. SB 32 covers certain United Instruments 5934 altimeters on listed serials (3244 to 3264 range), which may read higher than actual altitude.
