[Federal Register Volume 59, Number 109 (Wednesday, June 8, 1994)] [Unknown Section] [Page 0] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 94-13850] [[Page Unknown]] [Federal Register: June 8, 1994] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION 14 CFR Part 39 [Docket No. 93-CE-33-AD; Amendment 39-8936; AD 94-12-08] Airworthiness Directives: Cessna Aircraft Company 210, P210, and T210 Series Airplanes AGENCY: Federal Aviation Administration, DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: This amendment supersedes Airworthiness Directive (AD) 92-26- 04, which applies to certain Cessna Aircraft Company (Cessna) 210, P210, and T210 series airplanes. That AD requires operational checks of the fuel gauges, fuel cap and adapter modifications, and preflight fuel system quantity checks. The Federal Aviation Administration (FAA) received a petition for reconsideration of AD 92-26-04, and subsequently suspended the effectiveness of this AD while the concerns specified in the petition were evaluated. This action retains certain requirements of AD 92-26-04, and incorporates certain items raised by the petition for reconsideration. The actions specified by this AD are intended to prevent loss of engine power caused by inadvertent fuel loss or inadequate fuel servicing. DATES: Effective July 22, 1994. The incorporation by reference of certain publications listed in the regulations was previously approved by the Director of the Federal Register as of January 22, 1993. ADDRESSES: Service information that applies to this AD may be obtained from the Cessna Aircraft Company, Customer Services, P.O. Box 1521, Wichita, Kansas 67201. This information may also be examined at the FAA, Central Region, Office of the Assistant Chief Counsel, room 1558, 601 E. 12th Street, Kansas City, Missouri 64106; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC. FOR FURTHER INFORMATION CONTACT: Mr. Paul O. Pendleton, Aerospace Engineer, FAA, Wichita Aircraft Certification Office, 1801 Airport Road, room 100, Wichita, Kansas 67209; telephone (316) 946-4143; facsimile (316) 946-4407. SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Cessna 210, P210, and T210 series airplanes was published in the Federal Register on August 24, 1993 (58 FR 44621). The action proposed to supersede AD 92-26-04, Amendment 39-8431 (57 FR 57658, December 7, 1992), with a new AD that would require the following on Cessna 210, P210, and T210 series airplanes:Retain the fuel gauge operational checks, fuel cap and adapter modifications, and preflight fuel system quantity checks currently required by AD 92-26-04; Provide the option of utilizing approved alternative procedures for calibrating the fuel systems; Provide the option of accomplishing fuel capacity checks after refueling the airplane or installing raised fuel caps; and Revise the applicability of the actual AD to more fully clarify which airplanes are affected. Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the comments received. Several commenters state that the calibration procedures proposed are ineffective, very expensive, and the equipment necessary to accomplish the calibration is unavailable. Two of these commenters referenced calibration and gauge accuracy procedures that they felt were more realistic (more effective, less expensive, and available) than those specified in the proposal. The FAA (1) reviewed the procedures submitted by the commenters; (2) determined that the referenced procedures are, at least, as realistic as those proposed; and (3) incorporated the procedures into the AD. One commenter recommends limiting the number of hours of operation before an airplane equipped with uncalibrated fuel gauges must refuel. The commenter states that this would reduce the cost associated with requiring accurate fuel gauge calibration. The FAA concurs and has added this provision to the AD. Several commenters suggest increasing the pilots' knowledge of the fuel system limitations through training and advisories. The FAA concurs that this step is essential for aviation safety; however, AD's are utilized to correct an unsafe condition that exists or is likely to develop in aircraft of the same type design. Appropriate fuel system placarding (specified in the proposed AD) does provide an advisory to the limitations of the originally certificated fuel system, which could help increase pilot knowledge. Any other action related to increasing the pilot's knowledge of fuel system limitations is outside the scope of AD action. The AD is unchanged as a result of this comment. One commenter recommends that the FAA not require replacement of the flush fuel caps because the existing fuel caps are acceptable if they are properly maintained. The FAA concurs. The proposal included the option of installing these raised fuel caps or fabricating and installing a fuel capacity check placard on each wing fuel filler opening. The AD is unchanged as a result of this comment. One commenter recommends requiring replacement of the fuel caps with caps that are not susceptible to fuel leakage or siphoning and where certificated fuel capacity is easily obtainable. This commenter states that service experience indicates that the fuel caps originally certificated on these Cessna 210 series airplanes make fuel servicing difficult and susceptible to water leakage into the tanks and fuel siphoning during flight. The FAA does not concur that mandatory fuel cap replacement is necessary. The FAA has determined that the accomplishment of certain preflight requirements will provide the same level of safety as fuel cap replacement. The FAA encourages fuel cap replacement and the preflight requirements are reduced when replacement is accomplished. The AD is unchanged as a result of this comment. After careful review of all available information including the comments noted above, the FAA has determined that air safety and the public interest require the adoption of the rule as proposed except for the incorporation of the calibration and gauge accuracy procedures referenced above and minor editorial corrections. The FAA has determined that these procedures and minor corrections will not change the meaning of the AD nor add any additional burden upon the public than was already proposed. The FAA estimates that 5,000 airplanes in the U.S. registry will be affected by this AD, that it will take approximately 4 workhours per airplane to accomplish the required action, and that the average labor rate is approximately $55 an hour. Parts cost approximately $150 per airplane. Based on these figures, the total cost impact of the AD on U.S. operators is estimated to be $1,850,000. This figure is based on the assumption that no affected airplane owner/operator has accomplished the required action. In addition, AD 92-26-04 currently has a cost impact of $2,125,000 (5 workhours x $55 per hour plus $150 for parts x 5,000 airplanes) if the FAA had not suspended the effectiveness of that AD. The cost of this AD is actually a reduction of one workhour per airplane over that specified in AD 92-26-04, or a reduction of $275,000 for the entire U.S. fleet. 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. 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 copy of the final evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
