Airworthiness Directives; Meggitt (Troy), Inc. Combustion Heaters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede Airworthiness Directive (AD) 81-09-09, 
which applies to certain Meggitt (Troy), Inc. (previously known as 
Stewart Warner South Wind Corporation and as Stewart Warner South Wind 
Division) Model Series 8240 (Models 8240-A, 8240-C, 8240E, and 8248), 
8253 (Models 8253-A, 8253-B, and 8253-C), 8259 (Models 8259-A, 8259-C, 
8259-DL, 8259HL2, 8259HR2, 8259JR2, 8259L, and 8259M), and 8472 (Models 
8472C and 8472D) combustion heaters. AD 81-09-09 currently requires 
repetitive inspections of the combustion heater; repetitive general 
inspections of the combustion heater installation; and, for combustion 
heaters having 1,000 hours or more time-in-service (TIS), overhaul of 
the combustion heater. Since we issued AD 81-09-09, there was an 
airplane accident, and we received reports of the heater malfunction. 
This proposed AD would retain most actions from AD 81-09-09, add a 
calendar time to the repetitive inspections, and add more detailed 
actions for the general inspection. We are proposing this AD to correct 
the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by October 6, 2014.

Discussion

    On April 16, 1981, we issued AD 81-09-09, Amendment 39-4102 (46 FR 
24936, May 4, 1981) (``AD 81-09-09''), for certain Meggitt (Troy), Inc. 
(previously known as Stewart Warner South Wind Corporation and as 
Stewart Warner South Wind Division) Model Series 8240 (Models 8240-A, 
8240-C, 8240E, and 8248), 8253 (Models 8253-A, 8253-B, and 8253-C), 
8259 (Models 8259-A, 8259-C, 8259-DL, 8259HL2, 8259HR2, 8259JR2, 8259L, 
and 8259M), and 8472 (Models 8472C and 8472D) combustion heaters marked 
as meeting the standards of FAA TSO-C20. AD 81-09-09 requires 
repetitive inspection of the combustion heater and inspection of the 
installation of the combustion heater. AD 81-09-09 resulted from a 
hazardous condition caused by deterioration of the combustion heater. 
We issued AD 81-09-09 to detect and correct a hazardous condition 
caused by deterioration of the combustion heater, which could lead to 
ignition of components and result in smoke and fumes in the cabin.

Actions Since AD 81-09-09 Was Issued

    Since we issued AD 81-09-09, Amendment 39-4102 (46 FR 24936, May 4, 
1981), we received a report of an airplane accident that resulted in 
four fatalities and one serious injury. Only the survivor of the 
accident provided a written statement of the accident. She reported 
that when the pilot turned on the heater, a ``terrible smell'' was 
detected. The pilot told the passengers that the smell was normal for 
some heaters. When the pilot turned the heater off, dark, black smoke 
began to enter the airplane, which made it difficult to see. In a 
flight prior to the accident flight, the heater's overheat light 
illuminated when the heater was

[[Page 49250]]

turned on. The airplane maintenance records indicated a previous 
problem with the heater.
    Regardless of whether the heater played a part in the above-
referenced accident, this condition of deteriorated ignition components 
and smoke and fumes in the cabin could lead to passenger injury on 
other airplanes incorporating such heaters if not inspected and 
corrected.
    Since the accident, Meggitt, Inc. issued new service information 
for doing a pressure decay test (PDT). It was also identified that the 
repetitive inspections for the combustion heater required only time-in-
service inspections and did not include a calendar time compliance.

Relevant Service Information

    We reviewed:
     Stewart-Warner South Wind Corporation South Wind Service 
Manual for Stewart Warner South Wind Aircraft Heaters 8240-A, 8240-C, 
8259-A, 8259-C, 8259-DL, 8259-FL1, 8259-GL1, 8259-GL2, Form No. 09-998, 
revised: December 1969;
     South Wind Division Stewart-Warner Corporation Beech 
Aircraft Corporation Service Manual PM-20688, Part No. 404-001039 
Heater Assy. (SW 8253-B), revised: April 1965;
     South Wind Division Stewart-Warner Corporation Service 
Manual South Wind Aircraft Heater 8472 Series, Form No. 09-1015, 
issued: April 1975; and
     Meggitt Inspection Procedure, Pressure Decay Test, 
Aircraft Heaters, dated May 17, 2014.
    The service information describes procedures for inspection of the 
combustion heater, inspection of the installation of the combustion 
heater, and the pressure decay test for aircraft heaters.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would retain certain requirements of AD 81-09-09. 
This proposed AD would continue requiring the inspection of the 
combustion heater; however, the repair of the combustion tube would be 
prohibited. This proposed AD would also require a repetitive combustion 
heater pressure decay test and a more detailed inspection of the 
combustion heater and components.

Change to AD 81-09-09

    Since AD 81-09-09 was issued, the AD format has been revised, and 
certain paragraphs have been rearranged. As a result, the corresponding 
paragraph identifiers have been redesignated in this proposed AD, as 
listed in the following table:

                      Revised Paragraph Identifiers
------------------------------------------------------------------------
                                           Corresponding requirement in

------------------------------------------------------------------------
Paragraph (a)..........................  Paragraph (g).
Paragraph (b)..........................  Paragraph (j).
------------------------------------------------------------------------

Differences Between This Proposed AD and the Service Information

    The proposed AD would prohibit repair of any defective combustion 
tube while the service information does not specify this.

Costs of Compliance

    We estimate that this proposed AD affects 6,000 combustion heaters 
installed on, but not limited to, Piper Aircraft, Inc. and Cessna 
Aircraft Company airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary combustion 
heater overhaul/disable/related replacement that would be required 
based on the results of the proposed inspection/test. We have no way of 
determining the number of aircraft that might need a combustion heater 
overhaul/disable/related replacement:

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

[[Page 49251]]

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 
rulemaking action.

Regulatory Findings

    We have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD 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.
    For the reasons discussed above, I certify that the proposed 
regulation:
    (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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.
