Airworthiness Directives; British Aerospace Models HP.137 Jetstream Mk.1, Jetstream Series 200, and Jetstream Series 3101 Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Supplemental notice of proposed rulemaking (NPRM); Reopening of the comment period.
SUMMARY: This document proposes to revise an earlier proposed airworthiness directive (AD) that applies to British Aerospace Models HP.137 Jetstream Mk.1, Jetstream Series 200, and Jetstream Series 3101 airplanes. This proposed AD would supersede Airworthiness Directive (AD) 98-13-03, which currently requires repetitive inspections of the main landing gear (MLG) hinge fittings, support angles, and attachment bolts and requires eventual installation of improved design MLG hinge fittings as terminating action for the repetitive inspections of the hinge fittings and attachment bolts. AD 98-13-03 specifies repetitive inspections of the support angles for those airplanes with the improved design MLG hinge fittings installed and exempts from the applicability those airplanes with the improved design MLG hinge fittings installed. The earlier NPRM would have retained the requirements of AD 98-13-03 and would have removed the applicability exemption of those Models HP.137 Jetstream Mk.1 and Jetstream Series 200 airplanes with the improved design MLG hinge fittings installed. British Aerospace has informed us that it will not provide the improved design MLG hinge fittings free of charge. Since the cost burden has changed from the manufacturer to the owners/operators of the affected airplanes, we are reopening the comment period to allow the public the chance to comment on this additional cost burden.
DATES: The Federal Aviation Administration (FAA) must receive any comments on this proposed rule on or before December 21, 2001.
ADDRESSES: Submit comments to FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2000-CE-58-AD, 901 Locust, Room 506, Kansas City, Missouri 64106. You may view any comments at this location between 8 a.m. and 4 p.m., Monday through Friday, except Federal holidays.

Discussion
Has FAA taken any action on the main landing gear (MLG) hinge fittings, support angles, and attachment bolts on British Aerospace Models HP.137 Jetstream Mk.1, Jetstream Series 200, and Jetstream Series 3101 airplanes to this point? On June 8, 1998, FAA issued
[[Page 57892]]
AD 98-13-03, Amendment 39-10591 (63 FR 33532, June 19, 1998). This AD currently requires the following on the above-referenced airplanes:
--Repetitive inspections of the MLG hinge fitting, support angles, and attachment bolts, and repairing or replacing any part that is cracked; and --Eventual installation of improved design MLG hinge fittings, part number (P/N) 1379133B1 and 1379133B2 (Modification 5218), as terminating action for the repetitive inspections of the hinge fittings and attachment bolts. This AD specifies repetitive inspections of the support angles for those airplanes with the improved design MLG hinge fittings installed. However, the applicability of AD 98-13-03 exempts those airplanes with the improved design MLG hinge fittings installed from the actions of the AD.
Accomplishment of these actions is required in accordance with the following service information:
--British Aerospace Jetstream Mandatory Service Bulletin (MSB) No. 7/5, which includes procedures for inspecting the left and right main landing gear hinge attachment nuts to the auxiliary and aft spars for signs of relative movement between the nuts and hinge fitting on Models HP.137 Jetstream Mk.1 and Jetstream Series 200 airplanes.

The actions of AD 98-13-03 are consistent with our aging commuter aircraft policy, which briefly states that, when a modification exists that could eliminate or reduce the number of required critical inspections, the modification should be incorporated. This policy is based on our determination that reliance on critical repetitive inspections on airplanes utilized in commuter service carries an unnecessary safety risk when a design change exists that could eliminate or, in certain instances, reduce the number of those critical inspections.
The alternative to installing improved design MLG hinge fittings would be to repetitively inspect this area for the life of the airplane.
What has happened since AD 98-13-03 to initiate this action? Since AD 98-13-03 became effective, FAA has received comments regarding the applicability. The applicability of AD 98-13-03 exempts those airplanes with the improved design MLG hinge fittings installed as of the effective date of the AD. However, those airplanes that have the improved design MLG hinge fittings incorporated after the effective date of the AD are subject to repetitive inspections of the MLG support angles. Our intent was to require the inspections of the MLG support angles regardless of when the improved design MLG hinge fittings are incorporated.
Therefore, we then determined that the exemption of those airplanes with the improved design MLG hinge fittings installed should be removed, and that all affected airplanes should have the MLG support angles repetitively inspected.
Has FAA taken any action to this point? We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain British Aerospace Models HP.137 Jetstream Mk.1, Jetstream Series 200, and Jetstream Series 3101 airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on July 18, 2001 (66 FR 37435). The NPRM proposed to supersede AD 98-13-03. The NPRM also proposed to:
--Retain the requirement of repetitively inspecting the main landing gear (MLG) hinge fittings, support angles, and attachment bolts and the
[[Page 57893]]
requirement of repairing any cracked part; --Require eventual installation of improved design MLG hinge fittings as terminating action for the repetitive inspections of the hinge fittings and attachment bolts; and --Require repetitive inspections of the MLG support angles on all affected airplanes, even those with the improved design MLG hinge fittings installed.
Was the public invited to comment? The FAA encouraged interested persons to participate in the making of this amendment. The following presents the comments received on the proposal and FAA's response to each comment:
Comment Issue No. 1: Change or Clarify the Applicability for the Model Jetstream 3101 Series Airplanes
What is the commenter's concern? Two commenters question FAA's intent for the Model Jetstream 3101 Series airplanes, as follows:
--One commenter states that the AD should not require repetitive inspections of the support angles on the Model Jetstream 3101 Series airplanes once Modification JM5218 is incorporated. This commenter explains that this is explained in the most recent revised pages (Revision 5) of Jetstream SB 57-JM 5218. --Another commenter states that we should have extended the applicability to all serial numbers of the Jetstream 3101 Series airplanes if we wanted the support angles of all post-modification 5218 MLG fittings inspected. British Aerospace incorporated these fittings at the factory beginning with serial number 696. The applicability of the NPRM covered Model Jetstream 3101 Series airplanes up to serial number 695.
What is FAA's response to the concern? We concur that the AD should reflect that the repetitive inspections of the support angles do not apply to Model Jetstream Series 3101 airplanes that have Modification JM5218 incorporated. At the time of issuing the NPRM, we did not have the revised pages (Revision 5) of that service bulletin.
We are changing this proposed AD to reflect this change.
Making this change also takes care of the concern for requiring the inspections on those Model Jetstream Series 3101 airplanes that have serial number of 696 or higher. Since these airplanes had Modification JM5218 incorporated at the factory, the repetitive inspections of the support angles are not necessary.
The need for the repetitive inspections of the support angles on Models HP.137 Jetstream Mk.1 and Jetstream Series 200 airplanes still exists.
Comment Issue No. 2: Change the Cost Information To Reflect That British Aerospace Will Not Provide MLG Fittings Free of Charge
What is the commenter's concern? One commenter states that, because British Aerospace considers Modification JM5218 optional, the company is not providing the MLG fittings at no cost, as indicated in the NPRM. The current cost of these parts is $14,000 per airplane.
What is FAA's response to the concern? The FAA will revise the Cost Impact section of the final rule AD to reflect this change. Because this shifts the cost burden of these improved design MLG hinge fittings from the manufacturer to the owner/operator, we will reopen the comment period for this proposed AD.
Comment Issue No. 3: Require the Incorporation of Modification JM5218 to Reflect the Aging Aircraft Policy
What is the commenter's concern? One commenter states that FAA should mandate the incorporation of Modification JM5218 in order to be consistent with the agency's aging aircraft policy. This policy briefly states that, when a modification exists that could eliminate or reduce the number of required critical inspections, the modification should be incorporated. The policy is based on FAA's determination that reliance on critical repetitive inspections on airplanes utilized in commuter service carries an unnecessary safety risk when a design change exists that could eliminate or, in certain instances, reduce the number of those critical inspections.
What is FAA's response to the concern? Paragraph (d)(3) of the NPRM currently requires installing improved design MLG hinge fittings, part number (P/N) 1379133B1 (or FAA-approved equivalent P/N) and P/N 1379133B2 (or FAA-approved equivalent P/N) upon accumulating 20,000 landings on each MLG hinge fitting or within the next 50 landings after June 8, 1998 (the effective date of AD 98-13-03), whichever occurs later. These installations are Modification JM5218 so the commenter's concern is already incorporated in the NPRM.
We will add a statement in this proposed AD to indicate that these installations and Modification JM5218 are the same.
The FAA's Determination
What has FAA decided? After examining the circumstances and reviewing all available information related to the incidents described above, we have determined that:
--The unsafe condition exists or could develop on British Aerospace Models HP.137 Jetstream Mk.1, Jetstream Series 200, and Jetstream Series 3101 airplanes; --The comment period should be reopened to allow the public the opportunity to comment on the change in the cost impact; and --AD action should still be taken in order to correct this unsafe condition.
The Supplemental NPRM
How will the changes to the NPRM impact the public? Since British Aerospace is not providing the MLG fittings free of charge as indicated in the NPRM, the $14,000 burden for these parts is on the owners/ operators of the affected airplanes. Because this shifts the cost burden of these improved design MLG hinge fittings from the manufacturer to the owner/operator, we will reopen the comment period for this proposed AD.
What are the provisions of the supplemental NPRM? The provisions of this supplemental NPRM are the same as previously published.
Cost Impact
How many airplanes does this AD impact? We estimate that this AD affects 236 airplanes in the U.S. registry.
What is the cost impact of this AD on owners/operators of the affected airplanes? The FAA estimates that this AD will affect 71 airplanes in the U.S. registry. We estimate the following costs to accomplish the actions:
Labor cost
Parts cost Per airplane cost Fleet cost

Regulatory Impact
Would this proposed AD impact various entities? The regulations proposed herein 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. Therefore, it is determined that this proposed rule would not have federalism implications under Executive Order 13132.
Would this proposed AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this proposed 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) if promulgated, 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 copy of the draft regulatory evaluation prepared for this action has been placed in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
