Airworthiness Directives; Rolls-Royce plc RB211-524 and -535 Series Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211-524 and -535 series turbofan engines. This proposed AD would require initial and repetitive fluorescent penetrant inspections (FPI) and borescope inspections of the high pressure (HP) compressor stage 1 and 2 rotor discs for cracks. This proposed AD results from reports of low-cycle-fatigue cracks found at overhaul in the interface weld between the HP compressor stage 1 and 2 rotor disc. We are proposing this AD to prevent uncontained engine failure and damage to the airplane.
Airworthiness Directives; Lycoming Engines (L)O-360, (L)IO-360, AEIO-360, O-540, IO-540, AEIO-540, (L)TIO-540, IO-580, and IO-720 Series Reciprocating Engines.
The FAA is adopting a new airworthiness directive (AD) for certain Lycoming Engines (L)O-360, (L)IO-360, AEIO-360, O-540, IO-540, AEIO-540, (L)TIO-540, IO-580, and IO-720 series reciprocating engines. This AD requires replacing certain crankshafts. This AD results from reports of 23 confirmed failures of similar crankshafts in Lycoming Engines 360 and 540 series reciprocating engines. We are issuing this AD to prevent failure of the crankshaft, which will result in total engine power loss, in-flight engine failure, and possible loss of the aircraft.
Special Conditions: Boeing Model 767-300 Series Airplanes; Forward Lower Lobe Crew Rest Module (CRM)
These special conditions are issued for Boeing Model 767-300 series airplanes. These airplanes, modified by TIMCO Aviation Services, Inc. (TIMCO), will have a novel or unusual design feature associated with a forward lower lobe crew rest module (CRM). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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.
Airworthiness Directives; Air Tractor, Inc. Models AT-802 and AT-802A Airplanes
We are adopting a new airworthiness directive (AD) for certain Air Tractor, Inc. (Air Tractor) Models AT-802 and AT-802A airplanes. This AD requires you to repetitively inspect the attach angles on the firewall mounted hopper rinse tank shelf for damage and/or cracks and replace damaged and/or cracked attach angles with steel attach angles. Replacing the attach angles with steel attach angles terminates the repetitive inspection requirement. Reports of an uncommanded change in the engine power setting caused by separation of the hopper rinse tank shelf from the firewall prompted this AD. We are issuing this AD to detect and correct damage and/or cracks in the attach angles on the firewall mounted hopper rinse tank shelf, which could result in failure of the attach angles. This failure could lead to shelf movement under maneuver load and shifting of the engine power cables, which could result in an uncommanded engine power setting change.
Modification of Class E Airspace; Lake Ozark, MO
This document confirms the effective date of the direct final rule which revises Class E airspace at Lake Ozark, MO.
Establishment of Class E Airspace; Butler, GA
This action establishes Class E airspace at Butler, GA. Area Navigation (RNAV) Global Positioning System (GPS) and Nondirectional Radio Beacon (NDB) Standard Instrument Approach Procedures (SIAP) Runway (RWY) 18 and RWY 36 have been developed for Butler Municipal Airport. As a result, controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain the SIAPs and for Instrument Flight Rules (IFR) operations at Butler Municipal Airport. The operating status of the airport will change from Visual Flight Rules (VFR) to include IFR operations concurrent with the publication of the SIAP.
Modification of Class E Airspace; Chamberlain, SD
This action modifies Class E airspace at Chamberlain, SD. Standard Instrument Approach Procedures have been developed for Chamberlain Municipal Airport, Chamberlain, SD. Controlled airspace extending upward from 700 feet or more above the surface of the earth is needed to contain aircraft executing these approaches. This action increases the area of the existing controlled airspace for Chamberlain, SD.
Modification of Class E Airspace; Pierre, SD
This action modifies Class E airspace at Pierre, SD. Standard Instrument Approach Procedures have been developed for Pierre Regional Airport, Pierre, SD. Controlled airspace extending upward from 700 feet or more above the surface of the earth is needed to contain aircraft executing these approaches.This action increases the area of the existing controlled airspace for Pierre, SD.
Airworthiness Directives; General Electric Company CF34-10E Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF34-10E series turbofan engines. This AD requires removing the main fuel pump (MFP) inlet strainer from certain MFPs, installing a certain replacement flange as an interim repair, and performing initial and repetitive visual inspections of the main fuel filter. This AD results from three reports of release of the tripod support legs on the MFP inlet strainer, leading to engine in-flight shutdown. We are issuing this AD to prevent engine in-flight shutdown due to MFP malfunctions.
