INTEREST:
Service Bulletins, vendor manuals overhaul and maintenance manuals, which contain a statement that the document is
Transport Canada approved, are accepted by the FAA and are considered FAA approved. These approvals pertain to the
type design only.
NOTE 13. SPECIAL OPERATING PROCEDURES:
(1)-The PW120, PW120A, PW121, PW121A, PW123, PW123B, PW123C, PW123D, PW123E, PW124B, PW125B,
PW126A, PW127, PW127E, PW127F,PW126G, PW127M, PW127N, PW127XT-M and PW127XT-N models include
provisions for automatic power increase from Normal Takeoff Power to Maximum Takeoff Power. The limitations stated for
Normal Takeoff are to ensure that the Maximum Takeoff limitations are not exceeded in the event of an automatic power
increase to Maximum Takeoff power.
(2)-For all engine models takeoff ratings that are nominally limited to 5 minutes duration may be used for up to 10 minutes
for OEI operations without adverse effects upon engine airworthiness. Such operations are anticipated on an infrequent basis
(as engine failure at take-off events are uncommon) and no limits or special inspections have been imposed.
(3)-For the PW120, PW120A, PW121, and 123E models, the normal takeoff high pressure rotor speed limitation is variable
with ambient temperature to ensure the maximum spool speed is not exceeded in the event of an automatic power increase to
maximum takeoff. Refer to the Installation Manual for the normal takeoff limit.
(4)-Normal Takeoff ITT limitation is variable with ambient temperature for the following models: PW121A, PW123,
PW123B, PW123C, PW123D, PW123E, PW124B, PW125B, PW126A, PW127, PW127E, PW127F, PW127G, PW127M
PW127N, PW127XT-M and PW127XT-N. Refer to the applicable engine installation manual for the variable ITT limit.
(5)-The speed relationship between the low compressor spool and the high compressor spool is controlled by new engine
acceptance procedures and the Overhaul Manual for the PW120, PW120A, and PW121 and PW121A.
NOTE 14. SPECIAL REPAIR OR OVERHAUL LIMITATIONS:
