Airworthiness Directives; SOCATA--Groupe AEROSPATIALE Model TBM 700 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a new airworthiness directive (AD) that applies to certain SOCATA--Groupe AEROSPATIALE (Socata) Model TBM 700 airplanes equipped with Option No. OPT 70-35-001 (gaseous oxygen system). This AD requires you to incorporate a modification that relocates the oil breather vent location. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by this AD are intended to prevent oil from entering the gaseous oxygen system service compartment. Such oil contamination could result in a fire or explosion.

DATES: This AD becomes effective on May 11, 2001.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of May 11, 2001.

ADDRESSES: You may get the service information referenced in this AD from SOCATA Groupe AEROSPATIALE, Customer Support, Aerodrome Tarbes- Ossun-Lourdes, BP 930--F65009 Tarbes Cedex, France; telephone: (33) (0)5.62.41.73.00; facsimile: (33) (0)5.62.41.76.54; or the Product Support Manager, SOCATA--Groupe AEROSPATIALE, North Perry Airport, 7501 Pembroke Road, Pembroke Pines, Florida 33023; telephone: (954) 8941160; facsimile: (954) 964-4191.

SUPPLEMENTARY INFORMATION:

Discussion

What events have caused this proposed AD? The Direction Generale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, recently notified FAA that an unsafe condition may exist on certain Socata Model TBM 700 airplanes equipped with Option No. OPT 70- 35-001 (gaseous oxygen system). The DGAC communicates a report of oil entering the gaseous oxygen system service compartment on a Model TBM 700 airplane. In particular, oil was seeping out of the engine oil pump breather.

What are the consequences if the condition is not corrected? Such oil contamination could result in a fire or explosion.

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 Socata Model TBM 700 airplanes equipped with Option No. OPT 70-35-001 (gaseous oxygen system). This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on January 8, 2001 (66 FR 1271). The NPRM proposed to require you to relocate the oil breather vent location by incorporating Technical Instruction No. OPT70 K076-71 (Modification No. MOD70-119-71) ``OIL PUMP BREATHER''.

Was the public invited to comment? Interested persons were afforded an opportunity to participate in the making of this amendment. No comments were received on the proposed rule or the FAA's determination of the cost to the public.

FAA's Determination

What is FAA's final determination on this issue? After careful review of all available information related to the subject presented above, we have determined that air safety and the public interest require the adoption of the rule as proposed except for minor editorial corrections. We determined that these minor corrections:

--will not change the meaning of the AD; and --will not add any additional burden upon the public than was already proposed.

Cost Impact

How many airplanes does this AD impact? We estimate that 5 Model TBM 700 airplanes are on the U.S. Registry that could have a gaseous oxygen

[[Page 16845]]

system and could be affected by this AD.

What is the cost impact of this AD on owners/operators of the affected airplanes? We estimate the following costs to accomplish the modification:

Labor Cost--4 workhours x $60 = $240 Parts Cost--Socata will provide parts free of charge Total Cost Per Airplane--$240 Total Cost on U.S. Operators--$240 x 5 = $1,200.

Regulatory Impact

Does this AD impact various entities? 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.

Does this AD involve a significant rule or regulatory action? 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.
