14 CFR Part 39

Airworthiness Directives; Honeywell 

International, Inc. Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Honeywell International, Inc. ALF502L– 

2C; ALF502R–3; ALF502R–3A; 

ALF502R–5; LF507–1F; and LF507–1H 

turbofan engines. This AD was 

prompted by two reports of engines 

experiencing uncontained release of 

low-pressure (LP) turbine blades. This 

AD requires operational checks of the 

engine overspeed trip system. We are 

issuing this AD to prevent LP turbine 

overspeed leading to uncontained 

release of the LP turbine blades and 

damage to the airplane. 

DATES: This AD is effective July 5, 2012. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 

9 a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains this AD, the regulatory 

evaluation, any comments received, and

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM published in the Federal 

Register on March 9, 2012 (77 FR 

14312). That NPRM proposed to require 

operational checks of the engine 

overspeed trip system. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the one comment 

received. The National Transportation 

Safety Board supports the NPRM. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed, except that we determined 

to not incorporate by reference the 

engine manuals for the procedures for 

operational checks of the engine 

overspeed trip system. Instead, we have 

included those procedures in the AD. 

We have determined that these minor 

changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

14312, March 9, 2012) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 14312, 

March 9, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

188 Honeywell International, Inc. 

ALF502L–2C; ALF502R–3; ALF502R– 

3A; ALF502R–5; LF507–1F; and LF507– 

1H turbofan engines, installed on 

airplanes of U.S. registry. We also 

estimate that it will take about one 

work-hour to perform an operational 

check of the overspeed trip system on 

each engine. The average labor rate is 

$85 per work-hour. Based on these 

figures, we estimate the total cost of this 

AD for one operational check of the 

overspeed trip system to U.S. operators, 

to be $15,980. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701: 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will not have a 

substantial direct effect on the States, on 

the relationship between the national 

government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

(f) Initial Check of the Overspeed Trip 

System 

Within 30 operating hours after the

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.

(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

(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
