Inspection Of Exhaust System; Exhaust System Inspection Points - Piper Dakota Maintenance Manual

GENERAL
INSPECTION OF EXHAUST SYSTEM (figure 78-1)
All airplanes should be fitted with a new muffler at or near 1000
hours of muffler use.
The entire exhaust system, including heat exchange shroud, muff l e r, muffler baffles, stacks, and all
exhaust connections must be rigidly inspected at each annual or 100 hour inspection. The possibility of exhaust
system failure increases with use. The system must be checked more carefully as the number of hours
increases. The system must also be checked carefully before winter operation when the cabin heat will be in
use.
