Special Conditions: Aero Propulsion, Inc., Piper Model PA28-236; Diesel Cycle Engine Using Turbine (Jet) Fuel
These special conditions are issued to Aero Propulsion, Inc., for the Piper Model PA28-236 airplanes with a Societe de Motorisation Aeronautiques (SMA) Model SR305-230 Aircraft Diesel Engine (ADE). This airplane will have a novel or unusual design feature(s) associated with the installation of a diesel cycle engine utilizing turbine (jet) fuel. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for installation of this new technology engine. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Special Conditions; Cessna Aircraft Company Model 510 Airplane; Turbofan Engines and Engine Location
These special conditions are issued for the Cessna Aircraft Company, Model 510 airplane. This new airplane will have novel and unusual design features not typically associated with normal, utility, acrobatic, and commuter category airplanes. These design features include turbofan engines and engine location, for which the applicable regulations do not contain adequate or appropriate airworthiness standards. These special conditions contain the additional airworthiness standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Petitions for Exemption; Summary of Petitions Received
Pursuant to FAA's rulemaking provisions governing the application, processing, and disposition of petitions for exemption part 11 of Title 14, Code of Federal Regulations (14 CFR), this notice contains a summary of certain petitions seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of any petition or its final disposition.
Removal of References to Part 123 From 14 CFR Part 43
In the final rule, Certification and Operation Rules for Certain Large Airplanes, which the FAA published in the Federal Register on October 9, 1980, the FAA revoked part 123, effective January 1, 1983. However, references to part 123 remain in part 43. The purpose of this action is to remove those references. In addition, we are taking this opportunity to make some minor editorial corrections to part 43.
Airworthiness Directives; Pratt & Whitney PW4164, PW4168, and PW4168A Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Pratt & Whitney PW4164, PW4168, and PW4168A series turbofan engines. That AD currently requires initial and repetitive torque checks for loose or broken front pylon mount bolts made from INCO 718 material and MP159 material, and initial and repetitive visual inspections of the primary mount thrust load path. This AD requires the same actions, but at reduced intervals for front pylon mount bolts made from MP159 material. This AD results from analysis by the manufacturer that the MP159 material pylon bolts do not meet the full life cycle torque check interval requirement, in a bolt-out condition. We are issuing this AD to prevent front pylon mount bolt and primary mount thrust load path failure, which could result in an engine separating from the airplane.
