Summary
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737-200, -300, -400, and -500 series airplanes, that requires replacement of existing door handle mounting hub assemblies with new, improved hub assemblies. This amendment is prompted by reports of cracked or broken mounting hub assemblies for the interior door handles on the cabin doors. The actions specified by this AD are intended to prevent cracking or breaking of the door handle mounting hub, which could result in the interior door handle breaking off while the door is being opened. In an emergency situation, this could impede evacuation of the airplane.
The airworthiness directive
2000-14-13 Boeing: Amendment 39-11823. Docket 2000-NM-103-AD.
Applicability: Model 737-200, -300, -400, and -500 series airplanes; as listed in Boeing Service Bulletin 737-25-1322, Revision 2, dated February 19, 1998; certificated in any category.
Note 1:
This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
Compliance: Required as indicated, unless accomplished previously.
To prevent cracking or breaking of the door handle mounting hub, which could result in the interior door handle breaking off while the door is being opened, and, in an emergency situation, could impede evacuation of the airplane, accomplish the following:
(a) Replacement
PDF page 2(a) Within 18 months after the effective date of this AD, replace existing door handle mounting hub assemblies in the forward and aft entry doors, forward galley door, and aft service door, with new, improved hub assemblies, in accordance with Boeing Service Bulletin 737-25-1322, Revision 2, dated February 19, 1998.
Note 2:
Replacements accomplished prior to the effective date of this AD in accordance with Boeing Service Bulletin 737-25-1322, dated January 19, 1995, or Revision 1, dated December 19, 1996, are considered acceptable for compliance with paragraph (a) of this AD.
(b) Alternative Methods of Compliance
PDF page 2(b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Seattle ACO.
Note 3:
Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Seattle ACO.
(c) Special Flight Permits
PDF page 2(c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished.
(d) Incorporation by Reference
PDF page 2(d) The replacement shall be done in accordance with Boeing Service Bulletin 737-25-1322, Revision 2, dated February 19, 1998. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.

Supplementary informationPage 1
A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an airworthiness directive (AD) that is applicable to certain Boeing Model 737-200, -300, -400, and -500 series airplanes was published in the Federal Register on May 10, 2000 (65 FR 30019). That action proposed to require replacement of existing door handle mounting hub assemblies with new, improved hub assemblies.
CommentsPage 1
Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the comments received.
The commenters state no objections to the proposed rule.
ConclusionPage 1
After careful review of the available data, including the comments noted above, the FAA has determined that air safety and the public interest require the adoption of the rule as proposed.
Cost impactPage 1
There are approximately 1,575 airplanes of the affected design in the worldwide fleet. The FAA estimates that 632 airplanes of U.S. registry will be affected by this AD, that it will take approximately 12 work hours per airplane (3 work hours per door) to accomplish the required replacement, and that the average labor rate is $60 per work hour. Required parts will cost approximately $2,150 per airplane. Based on these figures, the cost impact of the AD on U.S. operators is estimated to be $1,813,840, or $2,870 per airplane.
The cost impact figure discussed above is based on assumptions that no operator has yet accomplished any of the requirements of this AD action, and that no operator would accomplish those actions in the future if this AD were not adopted. The cost impact figures discussed in AD rulemaking actions represent only the time necessary to perform the specific actions actually required by the AD. These figures typically do not include incidental costs, such as the time required to gain access and close up, planning time, or time necessitated by other administrative actions.
Regulatory impactPage 1
The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132.
For the reasons discussed above, I certify that this action (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); and (3) 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. A final evaluation has been prepared for this action and it is contained in the Rules Docket. A copy of it may be obtained from the Rules Docket at the location provided under the caption ADDRESSES.
Adoption of the amendmentPage 2
Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:
1. The authority citation for part 39 continues to read as follows:
2. Section 39.13 is amended by adding the following new airworthiness directive:
Affected TCDS · 1
The type certificate data sheets for the models this AD names, matched by model and maker.
Registered aircraft · 48
Registered aircraft whose airframe or engine model this AD names. Matched by model only, so check each against the AD’s applicability.
