[Federal Register: November 3, 2009 (Volume 74, Number 211)] [Rules and Regulations] [Page 56710-56713] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr03no09-6] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2008-1312; Directorate Identifier 2008-CE-065-AD; Amendment 39-16072; AD 2009-23-01] RIN 2120-AA64 Airworthiness Directives; Hawker Beechcraft Corporation Model 1900, 1900C, and 1900D Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Models 1900, 1900C, and 1900D airplanes. This AD requires a one-time visual inspection and repetitive ultrasonic inspections of the left and right main landing gear (MLG) actuators for leaking and/or cracks with replacement of the actuator if leaking and/ or cracks are found. This AD results from reports of leaking and cracked actuators. We are issuing this AD to detect and correct leaking and cracks in the MLG actuators, which could result in loss of hydraulic fluid. This condition could lead to an inability to extend or lock down the landing gear, which could result in a gear up landing or a gear collapse on landing. DATES: This AD becomes effective on December 8, 2009. On December 8, 2009, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION: Discussion On August 20, 2009, 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 Hawker Beechcraft Corporation Models 1900, 1900C, and 1900D airplanes. This proposal was published in the Federal Register as a supplemental notice of proposed rulemaking (NPRM) on August 31, 2009 (74 FR 44773). The NPRM proposed to require a one-time visual inspection and repetitive ultrasonic inspections of the left and right main landing gear (MLG) actuators for leaking and/or cracks with replacement of the actuator if leaking and/or cracks are found. Comments We provided the public the opportunity to participate in developing this AD. The following presents the comment received on the proposal and FAA's response to the comment: Comment Issue: Superseding Previous ADs Hawker Beechcraft Corporation requests that with this AD action we supersede AD 99-04-08 and AD 97-26-15, which affect earlier configurations of part number 114-380041 MLG actuator. They believe that one AD correcting all of the unsafe conditions concerned with the MLG actuator would eliminate confusion concerning which AD to comply with. The FAA disagrees. We did consider supersedure of the previous two ADs, AD 99-04-08 and AD 97-26-15. The previous two ADs and this new AD action each address different unsafe conditions on the MLG actuators. AD 99-04-08 concerns lubrication and replacement of the rod end, and AD 97-26-15 concerns replacement of the actuator head end cap. This new AD action concerns replacement of the rod end cap. AD 99-04-08 uses a prorated time of compliance starting with actuators that have accumulated 6,000 hours time-in-service and may still apply to low usage aircraft or aircraft that have been in storage. This current AD action specifies compliance based on actuator cycles. The only common feature in the three ADs is that the actuators were manufactured by Frisby Airborne Hydraulic, Inc. Based on the differences in the two previous ADs and in this new AD, we determined that combining the three into a single AD would confuse the unsafe conditions, rather than simplify them. If combined into one AD, each unsafe condition would still have different inspections, different [[Page 56711]] replacements, and different compliance times. To incorporate those differences into a single AD would create a complicated AD to understand. By keeping the AD actions separate, the corrective actions for each unsafe condition can be complied with individually. For these reasons, we decided a new AD action would be appropriate. We will not change the final rule AD action based on this comment. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial corrections. We have determined that these minor corrections: Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. Costs of Compliance We estimate that this AD affects 300 airplanes in the U.S. registry. The ultrasonic inspection includes the time allowed for removing and reinstalling the actuator. We estimate the following costs to do the inspections: ---------------------------------------------------------------------------------------------------------------- Total cost per Total cost on Labor cost Parts cost airplane U.S. operators ---------------------------------------------------------------------------------------------------------------- Visual Inspection: .5 work-hour x $80 per hour Not applicable.................. $40 $12,000 = $40. Ultrasonic Inspection: 6 work-hours x $80 per Not applicable.................. 480 144,000 hour = $480 (If the mechanic does not remove the actuator for the ultrasonic inspection, the labor cost will be less.). ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary replacements that would be required based on the results of the inspections. We have no way of determining the number of airplanes that may need this replacement: ------------------------------------------------------------------------ Total cost per Labor cost Parts cost airplane ------------------------------------------------------------------------ 6 work-hours x $80 per hour = $480 $4,600 per actuator. $5,080 (If the mechanic removes the actuator for the ultrasonic inspection, then the labor cost will be less.). ------------------------------------------------------------------------ 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 AD. Regulatory Findings We have determined that 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 the 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. We prepared a summary of the costs to comply with this AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include ``Docket No. FAA-2008-1312; Directorate Identifier 2008-CE-065-AD'' in your request. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment 0 Accordingly, under 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: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. FAA amends Sec. 39.13 by adding a new AD to read as follows: 2009-23-01 Hawker Beechcraft Corporation: Amendment 39-16072; Docket No. FAA-2008-1312; Directorate Identifier 2008-CE-065-AD.
