Airworthiness Directives; Maule Aerospace Technology, Inc. Airplanes


AGENCY:
 
Federal Aviation Administration (FAA), DOT.


ACTION:
 
Final rule.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
We are revising Airworthiness Directive (AD) 98-15-18 that applies to certain Maule


Aerospace Technology, Inc. Models M-4, M-5, M-6, M-7, MT-7, MX-7, MXT-7, and M-8 airplanes


that are equipped with rear wing lift struts, part number (P/N) 2079E, and/or front wing lift struts,


P/N 2080E. AD 98-15-18 required repetitively inspecting certain wing lift struts for internal


corrosion and replacing of any wing lift strut where corrosion was found. Since we issued AD 98-15-


18, we were informed by the manufacturer that Model MXT-7-420 airplanes are no longer in


existence, are no longer type certificated, and should be removed from the Applicability section. We


were also informed that paragraph (b) in AD 98-15-18 had been misinterpreted and caused confusion.


This AD removes Model MXT-7-420 airplanes from the Applicability section and clarifies the intent


of the language in paragraph (b) of AD 98-15-18. This AD also retains all other requirements of AD


98-15-18. We are issuing this AD to correct the unsafe condition on these products.


DATES:
 
This AD is effective January 21, 2014.


The Director of the Federal Register approved the incorporation by reference of a certain


publication listed in this AD as of January 26, 1996 (61 FR 623, January 9, 1996).

SUPPLEMENTARY INFORMATION:


Discussion


We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to revise AD 98-


15-18, Amendment 39-10669 (63 FR 39018, July 21, 1998), (''AD 98-15-18''). AD 98-15-18 was also


reissued with a correction on September 18, 1998 (63 FR 51520, September 28, 1998). AD 98-15-18


applied to the specified products. The NPRM published in the Federal Register on August 13, 2013


(78 FR 49207). The NPRM proposed to retain all requirements of AD 98-15-18, remove Model


MXT-7-420 airplanes from the Applicability section, and clarify our intent of required actions if the


seal on a sealed wing lift strut is ever improperly broken.


Comments


We gave the public the opportunity to participate in developing this AD. We received no


comments on the NPRM (78 FR 49207, August 13, 2013) or on the determination of the cost to the


public.


Conclusion


We reviewed the relevant data and determined that air safety and the public interest require


adopting this AD as proposed except for minor editorial changes. We have determined that these


minor changes:


•
 
Are consistent with the intent that was proposed in the NPRM (78 FR 49207, August 13,


2013) for correcting the unsafe condition; and


•
 
Do not add any additional burden upon the public than was already proposed in the NPRM


(78 FR 49207, August 13, 2013).


Costs of Compliance


We estimate that this AD affects 1,196 airplanes of U.S. registry.


We estimate the following costs to comply with this AD. However, the only difference in the


costs presented below and the costs associated with AD 98-15-18 is the change in the labor rate from


$65 per hour to $85 per hour.
