Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 727 

airplanes. This AD was prompted by 

certain mandated programs intended to 

support the airplane reaching its limit of 

validity of the engineering data that 

support the established structural 

maintenance program. This AD requires 

an inspection for cracks in the main 

wheel well pressure floor and a 

preventive modification or permanent 

repair, as applicable. We are issuing this 

AD to prevent cracking in the main 

wheel well pressure floor, which could 

result in reduced structural integrity of 

the airplane, and decompression of the 

cabin. 

DATES: This AD is effective May 1, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of December 14, 1992 (57 FR 53247, 

November 9, 1992).

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain The Boeing Company 

Model 727 airplanes. The NPRM 

published in the Federal Register on 

July 18, 2013 (78 FR 42900). The NPRM 

was prompted by certain mandated 

programs intended to support the 

airplane reaching its limit of validity of 

the engineering data that support the 

established structural maintenance 

program. The NPRM proposed to 

require an inspection for cracks in the 

main wheel well pressure floor and a 

preventive modification or permanent 

repair, as applicable. We are issuing this 

AD to prevent cracking in the main 

wheel well pressure floor, which could 

result in reduced structural integrity of 

the airplane, and decompression of the 

cabin. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (78 FR 42900, 

July 18, 2013) and the FAA’s response 

to each comment. 

Request To Clarify the Reason for 

Issuing the NPRM (78 FR 42900, July 

18, 2013) 

Boeing requested that we clarify a 

statement in the ‘‘Discussion’’ section of 

the preamble of the NPRM (78 FR 

42900, July 18, 2013). Boeing stated that 

the ‘‘Discussion’’ section in the 

preamble of the NPRM did not explain 

that the reason for proposing the NPRM 

was to complete one of the 

recommendations contained in Boeing’s 

727 Service Action Requirement 

Program. Boeing noted that in the 

NPRM’s ‘‘Discussion’’ section references 

were made to ‘‘certain programs’’ and 

‘‘previously established program,’’ but 

should have specifically referred to the 

Boeing 727 Service Action Requirement 

Program. Boeing also noted that the 

service information referenced in the 

NPRM is related to the Boeing 727 

Service Action Requirement Program. 

We agree that the references to 

‘‘certain programs’’ and ‘‘previously 

established program’’ were both 

referring to the Boeing 727 Service 

Action Requirement Program, and that 

the service information referenced in 

the NPRM (78 FR 42900, July 18, 2013) 

is related to that program. However, the 

portion of the NPRM’s ‘‘Discussion’’ 

section that Boeing referred to is not 

carried over into this final rule; 

therefore, no change to this final rule is 

necessary in this regard. 

Request To Correct Statements 

Regarding Other Relevant Rulemaking 

Boeing requested that we correct the 

statements regarding the AD 

requirements of the other relevant 

rulemaking mentioned in the preamble 

of the NPRM (78 FR 42900, July 18, 

2013). Boeing stated that the discussion 

regarding AD 92–19–11, Amendment 

39–8369 (57 FR 53247, November 9, 

1992), incorrectly stated that AD 92–19– 

11 required the preventative 

modification or permanent repair for 

airplanes having line numbers 001 

through 1432. Boeing noted that AD 92– 

19–11 did not require the preventative 

modification, but provided the option to 


sroberts on DSK5SPTVN1PROD with RULES
17010 Federal Register / Vol. 79, No. 59 / Thursday, March 27, 2014 / Rules and Regulations 

terminate the repetitive inspections if 

the preventative modification or 

permanent repair was installed on 

airplanes with line numbers 001 

through 1432. Boeing also stated that, in 

a different rulemaking action, the 

‘‘Other Relevant Rulemaking’’ section 

provided a clearer description of the 

actions required by AD 90–06–09, 

Amendment 39–6488 (55 FR 8370, 

March 7, 1990), and AD 92–19–11, and 

requested that the NPRM be revised to 

include the language from the other 

rulemaking action. 

We agree that the NPRM (78 FR 

42900, July 18, 2013) incorrectly stated 

that AD 92–19–11, Amendment 39– 

8369 (57 FR 53247, November 9, 1992), 

requires the preventive modification or 

permanent repair. However, in its 

comment, Boeing stated that the option 

to terminate the repetitive inspections 

provided in AD 92–19–11 was for 

airplanes having line numbers 001 

through 1432, which is not correct. AD 

92–19–11 provides the option to 

terminate the repetitive inspection 

requirements for all Model 727 

airplanes once the permanent repair or 

preventive modification is installed. 

We are issuing this final rule to 

require the permanent repair or 

modification for Model 727 airplanes 

with line positions 1433 through 1832 

inclusive. AD 90–06–09, Amendment 

39–6488 (55 FR 8370, March 7, 1990), 

only requires the permanent repair or 

terminating modification, in accordance 

with Boeing Service Bulletin 727–53– 

0149, Revision 2, dated March 20, 1981, 

which only applies to airplanes having 

line numbers 001 through 1432 

inclusive. AD 92–19–11, Amendment 

39–8369 (57 FR 53247, November 9, 

1992), does not require the permanent 

repair or terminating modification, but 

provides it as an option. 

The ‘‘Other Relevant Rulemaking’’ 

section of the NPRM (78 FR 42900, July 

18, 2013) is not carried over into this 

final rule; therefore, no change to this 

final rule is necessary in this regard. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

42900, July 18, 2013) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 42900, 

July 18, 2013). 

Costs of Compliance 

We estimate that this AD affects 106 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection ......................... 2 work-hours × $85 per hour = $170 ........................ $0 $170 ................................. $18,020. 

Modification/repair ............ Up to 272 work-hours × $85 per hour = $23,120 ..... 5,565 Up to $28,685 .................. Up to $3,040,610. 

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.

main wheel well pressure floor, which could 

result in reduced structural integrity of the 

airplane, and decompression of the cabin. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Definition of Detailed Inspection 

For the purposes of this AD, a detailed 

inspection is an intensive examination of a 

specific item, installation, or assembly to 

detect damage, failure, or irregularity. 

Available lighting is normally supplemented 

with a direct source of good lighting at an 

intensity deemed appropriate. Inspection 

aids such as mirrors, magnifying lenses, etc., 

may be necessary. Surface cleaning and 

elaborate procedures may be required. 

(h) Inspection and Repair/Modification 

At the later of the times specified in 

paragraphs (h)(1) and (h)(2) of this AD: Do a 

one-time detailed, high frequency eddy 

current (HFEC), or dye penetrant inspection 

for cracks in the main wheel well pressure 

floor at body stations 930, 940, and 950, 

between left and right buttock line 50 and the 

side of the airplane body, in accordance with 

the Accomplishment Instructions of Boeing 

Service Bulletin 727–53–0149, Revision 4, 

dated June 27, 1991. 

(1) Prior to the accumulation of 60,000 

total flight cycles; or 

(2) Within 2,500 flight cycles or 2 years 

after the effective date of this AD, whichever 

occurs first. 

Note 1 to paragraph (h) of this AD: If a 

detailed inspection is performed, stripping 

the paint will help ensure accurate 

inspection results. 

(i) Preventive Modification 

If no cracks are found during the 

inspection required by paragraph (h) of this 

AD: Before further flight, do the preventive 

modification, in accordance with Part IV of 

the Accomplishment Instructions of Boeing 

Service Bulletin 727–53–0149, Revision 4, 

dated June 27, 1991. Doing the preventive 

modification terminates the repetitive 

inspections required by paragraph (d) of AD 

92–19–11, Amendment 39–8369 (57 FR 

53247, November 9, 1992). 

(j) Permanent Repair 

If any crack is found during the inspection 

required by paragraph (h) of this AD: Before 

further flight, do the permanent repair, in 

accordance with Part III of the 

Accomplishment Instructions of Boeing 

Service Bulletin 727–53–0149, Revision 4, 

dated June 27, 1991. Doing the permanent 

repair terminates the repetitive inspections 

required by paragraph (d) of AD 92–19–11, 

Amendment 39–8369 (57 FR 53247, 

November 9, 1992). 

(k) Credit for Previous Actions 

This paragraph provides credit for actions 

required by paragraph (h) of this AD, if those 

actions were performed before the effective 

date of this AD using Boeing Service Bulletin 

727–53–0149, Revision 3, dated November 2, 

1989, which was incorporated by reference in 

AD 92–19–11, Amendment 39–8369 (57 FR 

53247, November 9, 1992). 

(l) Alternative Methods of Compliance
