Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2013–0025, 

dated February 6, 2013 (referred to 

herein after as ‘‘the MCAI’’), to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Several power loss events have been 

reported on Austro E4 engines, due to 

fracture of the waste gate controller lever. 

This condition, if not corrected, could lead 

to further cases of power loss events, possibly 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 78, No. 60 / Thursday, March 28, 2013 / Proposed Rules 18921 

resulting in forced landing, damage to the 

aeroplane and injury to occupants. 

We are proposing this AD to prevent 

engine power loss or in-flight shutdown, 

which could result in loss of control and 

damage to the airplane. You may obtain 

further information by examining the 

MCAI in the AD docket. 

Relevant Service Information 

Austro Engine GmbH has issued 

Mandatory Service Bulletin No. MSB– 

E4–007/3, Revision 3, dated November 

28, 2012. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of Austria, and is 

approved for operation in the United 

States. Pursuant to our bilateral 

agreement with Austria, EASA has 

notified us of the unsafe condition 

described in the MCAI and service 

information referenced above. We are 

proposing this AD because we evaluated 

all information provided by EASA and 

determined the unsafe condition exists 

and is likely to exist or develop on other 

products of the same type design. This 

proposed AD would require removing 

from service waste gate controllers, P/N 

E4A–41–120–000 Rev. 050 or lower, and 

waste gate controllers, P/N E4B–41– 

120–000 Rev. 000 during the next 

engine maintenance, or within 110 

flight hours or three months after the 

effective date of the AD, whichever 

occurs first. 

Costs of Compliance 

We estimate that this proposed AD 

affects 72 engines installed on airplanes 

of U.S. registry. We also estimate that it 

would take about one hour per engine 

to comply with this proposed AD. The 

average labor rate is $85 per hour. Based 

on these figures, we estimate the cost of 

the proposed AD on U.S. operators to be 

$6,120. Our cost estimate is exclusive of 

possible warranty coverage. 

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 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. Will not affect intrastate aviation in 

Alaska to the extent that it justifies 

making a regulatory distinction, 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 707–300, 

707–300B, and 707–300C series 

airplanes; and certain Model 727C, 727– 

100C, and 727–200F series airplanes. 

This proposed AD was prompted by a 

report that a cam latch on the main 

cargo door (MCD) broke during flight. 

This proposed AD would require 

performing repetitive inspections of the 

MCD cam latches; replacing cam 

latches, certain bolts, and door hinge 

fittings; performing related investigative 

and corrective actions, if necessary; and 

MCD rigging. We are proposing this AD 

to detect and correct cracked or 

damaged cam latches, latch pins, and 

latch pin cross bolts, which could 

reduce the structural integrity of the 

MCD, and result in rapid decompression 

of the airplane and potential loss of the 

MCD during flight. 

DATES: We must receive comments on 

this proposed AD by May 13, 2013. 

ADDRESSES: You may send comments,

Discussion 

We received a report that the forwardmost cam latch on the forward center 

cam latch pair (cam latch number 3) on 

the MCD broke during flight on a Model 

757 airplane. That airplane had 

accumulated 20,000 total flight hours 

and 9,500 total flight cycles when the 

cam latch broke. 

Certain Model 707–300, 707–300B, 

and 707–300C series airplanes; and 

certain Model 727C, 727–100C, and 

727–200F series airplanes; have an MCD 

with a similar design to the MCD on the 

Model 757 airplane. Therefore, those 

Model 707–300, 707–300B, and 707– 

300C series airplanes; and Model 727C, 

727–100C, and 727–200F series 

airplanes; might be subject to the unsafe 

condition revealed on Model 757 

airplanes. 

The MCD is an outward-hinging door 

that requires a locking mechanism to 

keep the door closed. The latch pins in 

the lower sill of the MCD interlock with 

the cam latches installed in the bottom 

of the MCD. When a latch pin interlocks 

with a cam latch, the cam latch rotates 

into the closed position and holds the 

door closed. We are proposing this AD 

to detect and correct cracked or 

damaged cam latches, latch pins, and 

latch pin cross bolts, which could 

reduce the structural integrity of the 

MCD, and result in rapid decompression 

of the airplane and potential loss of the 

MCD during flight.
