On September 15, 1995, the FAA issued priority letter Airworthiness Directive (AD) 95-20-01. This AD required the following on certain Beech Model 65 airplanes:
- fabricating a placard with the words "Operation of the airplane with the cabin door removed is prohibited";
- installing this placard on the airplane's instrument panel within the pilot's clear view; and
- incorporating a copy of this AD in the Limitations Section of the Airplane Flight Manual (AFM).
A recent accident of a Beech Model 65 airplane where the airplane was destroyed prompted that action. The referenced airplane was configured for parachute operations, including operating with the passenger seats and cabin door removed.
The operator of this airplane had the cabin door removed in accordance with FAA-approved Flight Manual Supplement, dated September 20, 1967. However, further examination of this particular flight manual supplement revealed an unapproved alterationof the document to make the Beech Model 65 eligible for operation with the cabin door removed.
The Type Certificate Data Sheet for the Beech 65 series airplanes lists several Beech Model airplanes that are eligible for cabin door removal. This listing does not include the Beech Model 65. Currently, the FAA is examining these circumstances to determine why this model was not included in this eligibility. Certain Beech Model 65 airplanes may operate with the cabin door removed under a Restricted Category Certificate.
The configuration of the Beech models that are eligible for operation with the cabin door removed includes a swept fin tail. The Beech Model 65 does not have this swept fin tail configuration. The FAA has not determined (1) the number of the 244 originally manufactured Beech Model 65 airplanes that are in operation with the cabin door removed in accordance with this Flight Manual Supplement, dated September 20, 1967; or (2) how many Restricted Category Certificates have been issued for operating with the cabin door removed.
After issuing AD 95-20-01, the FAA received reports that the Beech Model L-23F (military conversion) should also be included in the applicability of that AD. These airplanes are eligible to be brought back into civilian use. Based on this, the FAA determined that AD 95-20-01 should be revised to include these military conversion Beech Model L-23F airplanes.
Since an unsafe condition was identified that is likely to exist or develop in other Beech Models 65 and L-23F airplanes of the same type design (including those operating under a Restricted Category Certificate), the FAA revised priority letter AD 95-20-01 and issued priority letter AD 95-20-01 R1 to prevent the possibility of a reduction in stability, controllability, or airplane climb performance during operation, particularly in single-engine operations at high gross weights. The AD retains the placard and AFM requirements of AD 95-20-01 for the Model 65airplanes, and adds the Model L-23F airplanes to the Applicability section of the AD.
Since it was found that immediate corrective action was required, notice and opportunity for prior public comment thereon were impracticable and contrary to the public interest, and good cause existed to make the AD effective immediately by individual letters issued on September 21, 1995, to all known U.S. operators of Beech Models 65 and L-23F airplanes. These conditions still exist, and the AD is hereby published in the Federal Register as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13) to make it effective as to all persons.
Comments Invited
Although this action is in the form of a final rule that involves requirements affecting immediate flight safety and, thus, was not preceded by notice and opportunity to comment, comments are invited on this rule. Interested persons are invited to comment on this rule by submitting such written data, views, or arguments as they may desire. Communications should identify the Rules Docket number and be submitted in triplicate to the address specified above. All communications received on or before the closing date for comments will be considered, and this rule may be amended in light of the comments received. Factual information that supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether additional rulemaking action would be needed.
Comments are specifically invited on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify the rule. All comments submitted will be available, both before and after the closing date for comments, in the Rules Docket for examination by interested persons. A report that summarizes each FAA-public contact concerned with the substance of this AD will be filed in the Rules Docket.
Commenters wishing the FAA to acknowledge receipt of their comments submitted in response to this notice must submit a self-addressed, stamped postcard on which the following statement is made: "Comments to Docket No. 95-CE-76-AD." The postcard will be date stamped and returned to the commenter.
The regulations adopted herein will not have substantial direct effects 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, in accordance with Executive Order 12612, it is determined that this final rule does not have sufficient federalism implications to warrant the preparation of a Federalism Assessment.
The FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and is not a "significant regulatory action" under Executive Order 12866. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the Rules Docket. A copy of it, if filed, may be obtained from the Rules Docket at the location provided under the caption "ADDRESSES".
