that— 

(1) Includes the information specified 

in § 45.13 using an approved method of

that it will not likely be defaced or re-
moved during normal service, or lost or 
destroyed in an accident; and 

(3) Except as provided in paragraphs 

(d) through (h) of this section, must be 
secured to the aircraft fuselage exte-
rior so that it is legible to a person on 
the ground, and must be either adja-
cent to and aft of the rear-most en-
trance door or on the fuselage surface 
near the tail surfaces. 

(b) 

Aircraft engines. 

A manufacturer 

of an aircraft engine produced under a 
type certificate or production certifi-
cate must mark each engine by attach-
ing a fireproof identification plate. 
Such plate— 

(1) Must include the information 

specified in § 45.13 using an approved 
method of fireproof marking; 

(2) Must be affixed to the engine at 

an accessible location; and

hubs. 

Each person who produces a pro-

peller, propeller blade, or propeller hub 
under a type certificate or production 
certificate must mark each product or 
part. Except for a fixed-pitch wooden 
propeller, the marking must be accom-

method. The marking must— 

(1) Be placed on a non-critical sur-

face;

lope and must be located, if prac-
ticable, where it is legible to the oper-
ator when the balloon is inflated. In 
addition, the basket and heater assem-

paragraph (a) of this section. The plate 
must be secured at an accessible exte-
rior or interior location near an en-
