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.
Airworthiness Directives; Saab Model SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B Airplanes
This document revises an earlier proposed airworthiness directive (AD), applicable to certain Saab Model SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B airplanes, that would have required modification of the hot detection system of the tail pipe harness of the engine nacelles. This new action revises the original NPRM by reducing the compliance time for the modification and adding repetitive inspections. The actions specified by this new proposed AD are intended to prevent false warning indications to the flightcrew from the hot detection system due to discrepancies of the harness, which could result in unnecessary aborted takeoffs on the ground or an in-flight engine shutdown. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Learjet Model 45 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Learjet Model 45 airplanes. This proposed AD would require revising the Airworthiness Limitations section of the airplane maintenance manual to incorporate certain inspections and compliance times to detect fatigue cracking of certain principal structural elements (PSEs). This proposed AD results from new and more restrictive life limits and inspection intervals for certain PSEs. We are proposing this AD to ensure that fatigue cracking of various PSEs is detected and corrected; such fatigue cracking could adversely affect the structural integrity of these airplanes.
Modification of Class E Airspace; Keokuk Municipal Airport, IA
This action amends Title 14 Code of Federal Regulations, part 71 (14 CFR part 71) by modifying the Class E airspace area at Keokuk Municipal Airport, IA. The establishment of Area Navigation (RNAV) Global Positioning System (GPS) Instrument Approach Procedures (IAP) to Runways (RWY) 8, 14, 26 and 32 and amendments to existing Non- directional Beacon (NDB) IAPs to RWY 14 and 26 requires the modification of the Class E airspace area beginning at 700 feet above ground level (AGL). This airspace area and the legal description are modification to conform to the criteria in FAA Orders.
Proposed Establishment of Class E5 Airspace; Higginsville, MO
This notice proposes to amend part 71 of the Federal Aviation Regulations (14 CFR part 71) by establishing a Class E airspace area extending upward from 700 feet above the surface at Higginsville Industrial Municipal Airport, MO.
Modification of Class E Airspace; Scottsbluff, Western Nebraska Regional Airport/William B. Heilig Field, NE
This action amends Title 14 Code of Federal Regulations, part 71 (14 CFR part 71) by revising Class E airspace areas at Scottsbluff, Western Nebraska Regional Airport/William B. Heilig Field, NE. The establishment of a Localizer/Distance Measuring Equipment (LOC/DME) Instrument Approach Procedure (IAP) to Runway (RWY) 12 requires the modification of the Class E airspace area beginning at 700 feet above ground level (AGL). This airspace area and the legal description are modified to conform to the criteria in the FAA Orders.
Airworthiness Directives; Bell Helicopter Textron Canada Model 222, 222B, 222U, 230, and 430 Helicopters
This amendment adopts a new airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (BHTC) model helicopters. This action requires initial and repetitive inspections of each tail rotor counterweight bellcrank (bellcrank) with a specified part number and serial number. If external damage, a crack, roughness, or looseness between the bearing set and bellcrank is found or if bearing set axial play exceeds 0.015 inch, this action requires replacing the bellcrank with an airworthy bellcrank with two prefix letters in the serial number. This amendment is prompted by reports of failure and subsequent loss of a weighted portion of the bellcrank and reports of certain replacement bellcranks having design flaws. The actions specified in this AD are intended to prevent bellcrank failure, loss of a weighted portion of the bellcrank, and subsequent loss of control of the helicopter.
Airworthiness Directives; Raytheon Aircraft Company 65, 90, 99, and 100 Series Airplanes
We are adopting a new airworthiness directive (AD) that supersedes AD 92-07-05, which applies to certain Raytheon Aircraft Company (Raytheon) (formerly Beech) 65, 90, 99, and 100 series airplanes. AD 92-07-05 currently requires you to inspect the rudder trim tab for proper moisture drainage provisions, and if the correct drainage provisions do not exist, before further flight, modify the rudder trim tab. This AD results from receiving and evaluating new service information that requires the actions of AD 92-07-05 for the added serial numbers LJ-1281 through LJ-1732 for the Model C90A airplanes. This AD retains all the actions of AD 92-07-05 and adds serial numbers LJ-1281 through LJ-1732 for the Model C90A airplanes in the applicability section. We are issuing this AD to prevent water accumulation in the rudder trim tab, which could result in a change in the mass properties and possibly a lower flutter speed of the airplane. A lower airplane flutter speed could result in failure and loss of control of the airplane.
