Discussion The FAA received reports of corrosion on the elevator and aileron balance PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 tubes. Aerostar Aircraft Corporation (Aerostar) reported that, during repair of a Model PA–60–601P airplane, corrosion was found on the balance tubes used in the elevator and aileron systems. Corrosion on balance tubes in the elevator and aileron system may be hidden by rubber boots. These balance tubes counteract the effects of cabin pressurization. The majority of the Aerostar PA–60 airplane fleet have pressurized cabins. After the finding on the first airplane, Aerostar inspected four additional airplanes in the PA–60 fleet. Aerostar reported four out of these five airplanes had corrosion on both the aileron and elevator balance tubes. This condition, if not addressed, could result in failure of the aileron and elevator balance tubes. This failure could cause the aileron and/or elevator balance tubes to jam and result in loss of control of the airplane. Related Service Information Under 1 CFR Part 51 The FAA reviewed Aerostar Service Bulletin SB600–138, dated August 30, 2018. The service bulletin contains procedures for repetitively inspecting the elevator and aileron balance tubes for corrosion and rust and replacing the tubes at a specified time and repetitively if necessary. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA’s Determination The FAA is proposing this AD because it evaluated all 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 require accomplishing the actions specified in the service information described previously. Differences Between This Proposed AD and the Service Information This proposed AD would not require completing the reply card and returning it to Aerostar as specified in Step 13 of Part II of the service information.

Discussion

    The FAA received reports of corrosion on the elevator and aileron 
balance tubes. Aerostar Aircraft Corporation (Aerostar) reported that, 
during repair of a Model PA-60-601P airplane, corrosion was found on 
the balance tubes used in the elevator and aileron systems. Corrosion 
on balance tubes in the elevator and aileron system may be hidden by 
rubber boots. These balance tubes counteract the effects of cabin 
pressurization. The majority of the Aerostar PA-60 airplane fleet have 
pressurized cabins. After the finding on the first airplane, Aerostar 
inspected four additional airplanes in the PA-60 fleet. Aerostar 
reported four out of these five airplanes had corrosion on both the 
aileron and elevator balance tubes. This condition, if not addressed, 
could result in failure of the aileron and elevator balance tubes. This 
failure could cause the aileron and/or elevator balance tubes to jam 
and result in loss of control of the airplane.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Aerostar Service Bulletin SB600-138, dated August 
30, 2018. The service bulletin contains procedures for repetitively 
inspecting the elevator and aileron balance tubes for corrosion and 
rust and replacing the tubes at a specified time and repetitively if 
necessary. This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

FAA's Determination

    The FAA is proposing this AD because it evaluated all 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 require accomplishing the actions specified 
in the service information described previously.

Differences Between This Proposed AD and the Service Information

    This proposed AD would not require completing the reply card and 
returning it to Aerostar as specified in Step 13 of Part II of the 
service information.

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.
    The FAA is 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 rulemaking action.

Regulatory Findings

    The FAA 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, 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.

List of Subjects in 14 CFR Part 39

    This AD applies to Aerostar Aircraft Corporation Model PA-60-
601P (Aerostar 601P), PA-60-602P (Aerostar 602P), and PA-60-700P 
(Aerostar 700P) airplanes, all serial numbers, certificated in any 
category.

(d) Subject

    Air Transport Association (ATA) of America Code 27; Flight 
Controls.

(e) Unsafe Condition

    This AD was prompted by reports of corrosion on the elevator and 
aileron balance tubes. The FAA is issuing this AD to detect 
corrosion on the elevator and aileron balance tubes. The unsafe 
condition, if not addressed, could result in failure of the aileron 
and elevator balance tubes, jamming of the aileron and/or elevator 
balance tubes, and loss of control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Repetitive Inspections

    Within 10 hours time-in-service after the effective date of this 
AD, inspect the elevator and aileron balance tubes for corrosion 
(pitting and flaking) and rust (discoloration) by following steps 1. 
through 3. of Part I (Inspection) of the Instructions in Aerostar 
Aircraft Corporation Service Bulletin SB600-138, dated August 30, 
2018 (Aerostar SB600-138). For each tube replaced as required by 
paragraph (h) of this AD, using a borescope, repeat the inspection 
within 10 years after replacing the tube and thereafter as follows:
    (1) At intervals not to exceed 10 years as long as no rust is 
found.
    (2) At intervals not to exceed 2 years if only rust is found 
(without any signs of corrosion).

[[Page 38340]]

(h) Replacements

    At the following compliance times, replace each elevator and 
aileron balance tube by following Part II (Replacement) of the 
Instructions in Aerostar SB600-138, except you are not required to 
report information to the manufacturer:
    (1) Before further flight if corrosion or rust is found (inside 
or outside the tubes) during the initial inspection required by 
paragraph (g) of this AD.
    (2) At the next 100-hour inspection or at the next annual 
inspection, whichever occurs first, if no corrosion and no rust is 
found (inside or outside the tubes) during the initial inspection 
required by paragraph (g) of this AD.
    (3) Before further flight if corrosion is found (inside or 
outside the tubes) during any repetitive inspection required by 
paragraph (g) of this AD.
