RETURNING ENGINE TO SERVICE AFTER INFLUENCE BY FIRE
General note An engine after influence by fire must be inspected, repaired or overhauled according to
the BRP-Rotax instructions for continued airworthiness.
Inspection • Inspect all systems for correct functioning.
NOTE
Prior to the detailed inspection, all parts should be cleaned and inspected for burn
penetration or melted materials.
If an engine was influenced by fire, first a visual inspection of all parts has to be done and
then a hardness test of all mechanical parts must be performed
(e. g.: crankcase, cylinder, cylinder heads etc.).
In most cases an overhaul is necessary, in this regard the engine has to be overhauled ac-
cording to the current Overhaul Manual (OHM) for the respective engine type. Overhaul
Manual (OHM) and its appendix is available for any appropriately rated person or entity on
request and by following the standards of the original manufacturer.
