If your T55-L-712 engine needs improvement, let us know. Send us an EIR. You, the user

are the only one who can tell us what you do not like about your equipment. Let us know why

A FSCAP is defined as a part, assembly, or installation procedure with one or more criti-

cal characteristics that if not conforming to the design data or quality requirements, could re-

sult in serious injury or death to the crew members and/or serious damage to the helicopter.

A critical characteristic is any dimension, tolerance, finish, material, manufacturing, as-

sembly, or inspection process, or other feature which, if not conforming or missing, could cause

failure or malfunction of the FSCAP.

Critical characteristics produced during the manufacturing process are termed manufac-

turing critical characteristics. Critical characteristics not introduced during manufacturing but

critical in terms of assembly/installation (e.g. proper torque) are termed installation critical char-

acteristics.

The following identifies parts, assemblies, or installations under the FSCAP Program,

requiring special handling during maintenance and lists all current flight safety parts. Parts may

not be repairable at field level.
