List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

2012–11–07 Honeywell International, Inc.: 

Amendment 39–17070; Docket No. 

FAA–2012–0195; Directorate Identifier 

2012–NE–08–AD. 

(a) Effective Date 

This AD is effective July 5, 2012. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Honeywell 

International, Inc. ALF502L–2C; ALF502R–3; 

ALF502R–3A; ALF502R–5; LF507–1F; and 

LF507–1H turbofan engines. 

(d) Unsafe Condition 

This AD was prompted by two reports of 

engines experiencing uncontained release of 

low-pressure (LP) turbine blades. We are 

issuing this AD to prevent LP turbine 

overspeed leading to uncontained release of 

the LP turbine blades and damage to the 

airplane. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(f) Initial Check of the Overspeed Trip 

System 

Within 30 operating hours after the 

effective date of this AD, perform an initial 

check of the overspeed trip system, in 

accordance with the applicable paragraphs 

for your engine as follows: 

(1) ALF502L–2C Engines 

(i) With engine operating at 65 percent NL 

(N1) speed (28 to 30 percent if overspeed 

controller 2–303–052–04 or later is installed), 

pull toggle lever of cockpit OVERSPEED 

TEST/RESET switch and hold in the 

OVERSPEED TEST position. 

(ii) Activation of the engine overspeed 

system shall be verified by: 

(A) Engine OVERSPEED TRIP light 

illuminated in cockpit. 

(B) Reduction of engine NH (N2) speed. 

(C) When engine NH (N2) speed begins to 

decrease, retract engine power lever to fuel 

cutoff position and turn off fuel boost pumps. 

(D) Release lever of engine cockpit 

OVERSPEED TEST/RESET Switch. 

(E) When engine is completely shut down, 

reset the engine Overspeed System by 

momentarily holding the engine cockpit 

OVERSPEED TEST/RESET switch on the 

RESET position. 

(F) If engine does not shut down, manually 

shut down engine and perform a detailed 

functional test of the overspeed system. 

Guidance on performing a detailed functional 

test of the overspeed system can be found in 

the applicable engine maintenance manual 

instructions. 

(2) ALF502R–3; ALF502R–3A; ALF502R–5, 

and LF507–1H Engines 

(i) With engine operating at ground idle, 

set engine NL (N1) speed to 30 to 35 percent. 

(ii) Press cockpit OVERSPEED TEST 

switch and hold. 

(iii) Activation of the engine overspeed 

system shall be verified by: 

(A) Engine OVERSPEED TRIP light 

illuminated in cockpit. 

(B) Shutdown of the engine [zero NH (N2) 

speed]. 

(iv) Release cockpit OVERSPEED TEST 

switch and retract power lever to fuel cutoff 

position. 

(v) When the engine is completely shut 

down, reset the engine overspeed system. 

(vi) If engine does not shut down, 

manually shut down engine and perform a 

detailed functional test of the overspeed 

system. Guidance on performing a detailed 

functional test of the overspeed system can 

be found in the applicable engine manual 

instructions. 

(3) LF507–1F Engines 

(i) With engine operating at ground idle, 

set engine NL (N1) speed to 30 to 35 percent. 

(ii) Activate cockpit overspeed test circuit 

(GRND TEST ENG OVSPD). 

(iii) After NL (N1) speed begins to decay, 

retard the throttle to the fuel cutoff position. 

(iv) Verify the following conditions: 

(A) Engine shutdown. 

(B) Overspeed system light (ENG OVSPD) 

is illuminated in cockpit. 

(v) Reset overspeed system circuit power. 

(vi) If engine does not shut down, 

manually shut down engine and perform a 

detailed functional test of the overspeed 

system. Guidance on performing a detailed 

functional test of the overspeed system can 

be found in the applicable engine manual 

instructions. 

(g) Repetitive Checks of the Overspeed Trip 

System 

(1) For ALF502L–2C engines, perform 

repetitive checks of the overspeed trip system 

at 100-hour intervals of operation, as 

specified in paragraph (f)(1) of this AD. 

(2) For ALF502R–3; ALF502R–3A; 

ALF502R–5; and LF507–1H engines, perform 

repetitive checks of the overspeed trip system 

once every flight day, as specified in 

paragraph (f)(2) of this AD. 

(3) For LF507–1F engines, perform 

repetitive checks of the overspeed trip system 

once every flight day, as specified in 

paragraph (f)(3) of this AD. 

(h) Definition 

For the purpose of this AD, a flight day is 

a 24-hour period during which at least one 

flight is indicated. 

(i) Signing Off of Daily Repetitive Checks 

Upon starting the daily repetitive checks, 

only one sign-off is required attesting to the 

daily check implementation. 

(j) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Los Angeles Aircraft 

Certification Office, may approve AMOCs for 

this AD. Use the procedures found in 14 CFR 

39.19 to make your request.
