Federal Aviation Administration October 8, 2010 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Pratt & Whitney JT8D-9, -9A, -11, -15, -17, and -17R Turbofan Engines
Document Number: 2010-25391
Type: Rule
Date: 2010-10-08
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney (PW) JT8D-9, -9A, -11, -15, -17, and -17R turbofan engines. This AD requires overhauling fan blade leading edges at the first shop visit after 4,000 cycles-in-service (CIS) since the last total fan blade overhaul was performed. This AD results from reports of failed fan blades. We are issuing this AD to prevent high-cycle fatigue cracking at the blade root, which could result in uncontained failures of first stage fan blades and damage to the airplane.
Airworthiness Directives; Hamilton Sundstrand Propellers Model 247F Propellers
Document Number: 2010-25390
Type: Proposed Rule
Date: 2010-10-08
Agency: Federal Aviation Administration, Department of Transportation
This supplemental NPRM revises an earlier proposed airworthiness directive (AD) applicable to Hamilton Sundstrand Propellers model 247F propeller assemblies with certain part number (P/ N) and serial number (S/N) blades. That proposed AD would require removing affected propeller blades from service. That proposed AD resulted from reports of blades with corrosion pits in the tulip area of the blades. This supplemental NPRM revises the proposed AD to remove certain propeller S/Ns from the applicability requirement, and to add additional propeller S/Ns to the applicability requirement. This proposed AD results from the manufacture's latest service information containing propeller S/Ns that were not specified in the proposed AD. We are proposing this AD to prevent cracks from developing in the tulip area of the blade, which could result in separation of the blade and possible loss of airplane control.
Airworthiness Directives; McDonnell Douglas Corporation Model DC-9-14, DC-9-15, and DC-9-15F Airplanes; and DC-9-20, DC-9-30, DC-9-40, and DC-9-50 Series Airplanes
Document Number: 2010-25374
Type: Proposed Rule
Date: 2010-10-08
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require installing new in-line fuses for the fuel level float switch and new in-line fuses for the pressure switch, as applicable, and changing the wiring. The proposed actions would affect the left and right wing forward spars, center wing forward spar, forward auxiliary fuel tank, and aft auxiliary fuel tank, as applicable. This proposed AD was prompted by fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
