Type Certification Procedures for Changed Products
Document Number: 2012-29276
Type: Rule
Date: 2012-12-04
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising a final rule published on June 7, 2000 (65 FR 36244). In that final rule, the FAA amended its regulations for the certification of changes to type-certificated products. That amendment was to enhance safety by applying the latest airworthiness standards, to the extent practical, for the certification of significant design changes of aircraft, aircraft engines, and propellers. The existing rule requires the applicant show that the ``changed product'' complies with applicable standards. This action revises that requirement so that an applicant is required to show compliance only for the change and areas affected by the change. The intended effect of this action is to make the regulation consistent with the FAA's intent and with the certification practice both before and after the adoption of the existing rule.
Minimum Altitudes for Use of Autopilots
Document Number: 2012-29274
Type: Proposed Rule
Date: 2012-12-04
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to amend and harmonize minimum altitudes for use of autopilots for transport category airplanes. The proposed rule would enable the operational use of advanced autopilot and navigation systems by incorporating the capabilities of new and future autopilots, flight guidance systems, and Global Navigation Satellite System (GNSS) guidance systems while protecting the continued use of legacy systems at current autopilot minimum use altitudes. The proposed rule would accomplish this through a performance-based approach, using the certified capabilities of autopilot systems as established by the Airplane Flight Manual (AFM) or as approved by the Administrator.
Airworthiness Directives; The Boeing Company
Document Number: 2012-29177
Type: Proposed Rule
Date: 2012-12-04
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777-200 and -300 series airplanes. This proposed AD was prompted by reports of hydraulic fluid contamination found in the strut forward dry bay. This proposed AD would require repetitive general visual inspections of the strut forward dry bay for the presence of hydraulic fluid, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct hydraulic fluid contamination of the strut forward dry bay, which could result in hydrogen embrittlement of the titanium forward engine mount bulkhead fittings, and consequent inability of the fittings to carry engine loads, resulting in the loss or departure of an engine. Hydraulic embrittlement could cause a through-crack formation across the fittings through which an engine fire could breach into the strut, resulting in an uncontained strut fire.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2012-29171
Type: Proposed Rule
Date: 2012-12-04
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to certain Bombardier, Inc. Model DHC-8-400 series airplanes. The existing AD currently requires a free-play check for excessive free-play of the shaft swaged bearing installed in the tailstock end of each elevator power control unit (PCU), and replacing any PCU on which the bearing exceeds allowable limits with a serviceable PCU. Since we issued that AD, we have determined that additional airplanes are affected by the identified unsafe condition. This proposed AD would add airplanes to the applicability in the existing AD. We are proposing this AD to detect and correct excessive freeplay of the swaged bearings, which could lead to excessive airframe vibrations and difficulties in pitch control, and consequent loss of controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-29170
Type: Proposed Rule
Date: 2012-12-04
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 737-200, -200C, - 300, and -400 series airplanes. The existing AD currently requires repetitive inspections to detect cracking of the corners of the door frame and the cross beams of the aft cargo door, and corrective actions if necessary. The existing AD also requires a modification to the aft cargo door, which terminates the repetitive inspections. Since we issued that AD, we have received reports of cracking on doors on airplanes that were not included in the existing AD. This proposed AD would add airplanes to the applicability, add inspections and related investigative and corrective actions, and revise certain inspection types. This proposed AD would also reduce the compliance time, for certain doors, to do a modification of the doors. We are proposing this AD to prevent fatigue cracking of the corners of the door frame and the cross beams of the aft cargo door, which could result in rapid depressurization of the airplane.
Proposed Modification of the Miami, FL, Class B Airspace Area; and the Ft Lauderdale, FL, Class C Airspace Area; Public Meetings
Document Number: 2012-28991
Type: Proposed Rule
Date: 2012-12-04
Agency: Federal Aviation Administration, Department of Transportation
This notice announces three fact-finding informal airspace meetings to solicit information from airspace users and others, concerning a proposal to revise the Class B airspace at Miami, FL, and the Class C airspace at Ft Lauderdale, FL. The purpose of these meetings is to provide interested parties an opportunity to present views, recommendations, and comments on the proposal. All comments received will be considered prior to any issuance of a notice of proposed rulemaking.
