Vol. 75, No. 90

DEPARTMENT OF TRANSPORTATION 

Federal Aviation Administration 

14 CFR Part 39 

[Docket No. 95–NM–215–AD] 

RIN 2120–AA64 

Airworthiness Directives; The Boeing 

Company Model 737–100 and –200 

Series Airplanes 

AGENCY: Federal Aviation 

Administration, DOT. 

ACTION: Proposed rule; withdrawal. 

SUMMARY: This action withdraws a 

supplemental notice of proposed 

rulemaking (NPRM) that proposed a 

new airworthiness directive (AD), 

applicable to certain Model 737–100 

and –200 series airplanes. That action 

would have superseded an existing AD 

that requires various inspections for 

cracks in the outboard chord of the 

frame at body station (BS) 727 and in 

the outboard chord of stringer 18A; and 

repair or replacement of cracked parts. 

That action also would have added 

inspections for certain airplanes, revised 

certain compliance times for all 

airplanes, and added airplanes to the 

applicability. Since the issuance of the 

supplemental NPRM, the Federal 

Aviation Administration (FAA) has 

received revised service information 

that will significantly change the 

requirements proposed by the 

supplemental NPRM. Accordingly, the 

proposed rule is withdrawn.

SUPPLEMENTARY INFORMATION: A 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

add an airworthiness directive (AD), 

applicable to certain Model 737–100 

and –200 series airplanes, was 

published in the Federal Register as a 

supplemental Notice of Proposed 

Rulemaking (NPRM) on July 10, 2001 

(66 FR 35912). That supplemental 

NPRM proposed to supersede AD 95– 

12–17, Amendment 39–9268 (60 FR 

36981, July 24, 1995). That 

supplemental NPRM would have 

continued to require various inspections 

for cracks in the outboard chord of the 

frame at body station (BS) 727 and in 

the outboard chord of stringer 18A; and 

repair or replacement of cracked parts. 

That supplemental NPRM also would 

have added inspections for certain 

airplanes, revised certain compliance 

times for all airplanes, and added 

airplanes to the applicability. That 

supplemental NPRM was prompted by 

reports of fatigue cracks in those 

outboard chords. The proposed actions 

were intended to detect and correct 

fatigue cracking, which could result in 

reduced structural integrity of the 

outboard chords, and consequent rapid 

decompression of the airplane. 

Actions That Occurred Since the 

Supplemental NPRM Was Issued 

Since the issuance of that 

supplemental NPRM, The Boeing 

Company has issued revised service 

information that is significantly changed 

from the service information referenced 

in the supplemental NPRM. As a result, 

substantial changes to the requirements 

proposed in the supplemental NPRM 

are necessary. 

FAA’s Conclusions 

The FAA has determined that the best 

course of action is to withdraw the 

supplemental NPRM and issue a new 

NPRM with revised requirements 

referencing the updated service 

information. Accordingly, the proposed 

rule is hereby withdrawn. 

Withdrawal of this supplemental 

NPRM constitutes only such action, and 

does not preclude the agency from 

issuing another action in the future, nor 

does it commit the agency to any course 

of action in the future. 

Regulatory Impact 

Since this action only withdraws a 

supplemental NPRM, it is neither a 

proposed nor a final rule and therefore 

is not covered under Executive Order 

12866, the Regulatory Flexibility Act, or 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979).

The Withdrawal 

Accordingly, the supplemental 

NPRM, Docket No. 95–NM–215–AD, 

published in the Federal Register on 

July 10, 2001 (66 FR 35912), is 

withdrawn. 

Issued in Renton, Washington, on May 4,
