Sec. 125.147  Cowling.

    (a) Cowling must be made and supported so as to resist the 
vibration, inertia, and air loads to which it may be normally subjected.
    (b) Provisions must be made to allow rapid and complete drainage of 
the cowling in normal ground and flight attitudes. Drains must not 
discharge in locations constituting a fire hazard.

[[Page 993]]

Parts of the cowling that are subjected to high temperatures because 
they are near exhaust system parts or because of exhaust gas impingement 
must be made of fireproof material. Unless otherwise specified in these 
regulations, all other parts of the cowling must be made of material 
that is at least fire resistant.
