ACTION:
 
Final rule.


–––––––––––––––––––––––––––––––––––-


SUMMARY:
 
The FAA is revising Airworthiness Directive (AD) 2004-25-16, which applies to


aircraft equipped with a fuel regulator shutoff valve part number (P/N) 14D11, A14D11, B14D11,


C14D11, 23D04, A23D04, B23D04, C23D04, or P23D04 used with B1500, B2030, B2500, B3040,


B3500, B4050, or B4500 B-Series combustion heaters. AD 2004-25-16 currently requires you to


repetitively inspect the fuel regulator shutoff valve (visually or by pressure test) for fuel leakage and


replace the fuel regulator shutoff valve with an improved design replacement part with a


manufacturer's date code of 02/02 or later if fuel leakage is found. AD 2004-25-16 also allows you to


disable the heater as an alternative method of compliance. Since we issued AD 2004-25-16, we


received several comments requesting a revision to paragraph (e)(2). Consequently, this AD retains


the actions required in AD 2004-25-16 and revises the requirements in paragraph (e)(2) to remove a


required action. We are issuing this AD to prevent failure of the fuel regulator shutoff valve, which


could result in fuel leakage in aircraft with these combustion heaters. This failure could result in an


aircraft fire.


DATES:
 
This AD becomes effective on June 20, 2005.


On January 5, 2005 (69 FR 75228, December 16, 2004), the Director of the Federal Register


approved the incorporation by reference of Kelly Aerospace Power Systems Service Bulletin No. A-


107A, Issue Date: September 6, 2002; and Piper Vendor Service Publication VSP-150, dated January


31, 2003.

SUPPLEMENTARY INFORMATION:


Discussion


What events have caused this AD?
 
Reports of certain regulator shutoff valves leaking caused


FAA to issue AD 2001-08-01, Amendment 39-12178 (66 FR 19718, April 17, 2001). AD 2001-08-01


required you to visually inspect and pressure test the fuel regulator shutoff valves for leaks and


replace the fuel regulator shutoff valve if leaks were found.


The affected fuel regulator shutoff valves are part of the B1500, B2030, B2500, B3040, B3500,


B4050, and B4500 combustion heater configuration.


Operators of aircraft with the affected fuel regulator shutoff valves installed and mechanics who


did the actions of AD 2001-08-01 provided suggestions for improvement to the AD. Based on that


feedback, FAA superseded AD 2001-08-01 with AD 2001-17-13, Amendment 39-12404 (66 FR


44027, August 22, 2001).


AD 2001-17-13 retained the actions of AD 2001-08-01, except it required only the visual


inspection or the pressure test of the fuel regulator shutoff valves (not both) and listed the affected


fuel regulator shutoff valves by part number instead of series. AD 2001-17-13 also included a


provision for disabling the heater as an alternative method of compliance.


The FAA continued to receive reports of problems with these fuel regulator shutoff valves. This


service history reflects that the inspections should be repetitive instead of one-time. Based on this


information, FAA superseded AD 2001-17-13 with AD 2004-25-16, Amendment 39-13904 (69 FR


75228, December 16, 2004).


AD 2004-25-16 retains the actions required in AD 2001-17-13, makes the inspection repetitive,


and requires installing improved design replacement parts.


What has happened since AD 2004-25-16 to initiate this AD action?
 
We inadvertently retained


an action from AD 2001-17-13 and made it repetitive. After each inspection of the fuel regulator


shutoff valve for signs of fuel leaks and no leaks are found, AD 2004-25-16 requires the valve cover


to be marked with the date of inspection.


Since AD 2004-25-16 made that inspection repetitive, it is not feasible to mark the valve cover


with the date of each inspection. Therefore, we are revising AD 2004-25-16 to remove this action.


What is the potential impact if FAA took no action?
 
This condition, if not corrected, could result


in fuel leakage in aircraft with these combustion heaters, which could result in an aircraft fire with


consequent damage or destruction.


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 aircraft equipped with a


fuel regulator shutoff valve part number (P/N) 14D11, A14D11, B14D11, C14D11, 23D04, A23D04,


B23D04, C23D04, or P23D04 used with B1500, B2030, B2500, B3040, B3500, B4050, or B4500 B-


Series combustion heaters. This proposal was published in the Federal Register as a notice of


proposed rulemaking (NPRM) on March 9, 2005 (70 FR 11588). The NPRM proposed to revise AD


2004-25-16 with a new AD that would retain the actions required in AD 2004-25-16 and removes the


requirement to mark the valve cover with the date of inspection as specified in paragraph (e)(2) of the


AD.
