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 That action would have superseded an existing AD that requires various inspections for cracks in the outboard chord of the frame at body station (BS) 727 and in the outboard chord of stringer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 Accordingly, the proposed rule is withdrawn.

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.

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action would have superseded an existing AD that requires various 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, 2010.
