Airworthiness Directives; Sandel Avionics Incorporated Model ST3400 Terrain Awareness Warning System/Radio Magnetic

Fri, Jun 13 2008 11:00:00 GMT

The FAA is revising an existing airworthiness directive (AD) that applies to Sandel Avionics Incorporated Model ST3400 TAWS/RMI units as described above. The existing AD currently requires installing a warning placard on the TAWS/RMI and revising the Limitations section of the airplane flight manual (AFM). The existing AD also requires installing upgraded software in the TAWS/RMI. This new AD allows installing later revisions of the software described in the existing AD. This AD results from a report that an inflight bearing error occurred in a Model ST3400 TAWS/RMI configured to receive bearing information from a very high frequency omnidirectional range (VOR) receiver interface via a composite video signal, due to a combination of input signal fault and software error. We are issuing this AD to prevent a bearing error, which could lead to an airplane departing from its scheduled flight path, which could result in a reduction in separation from, and a possible collision with, other aircraft or

Establishment of Class E Airspace; Hinton, OK

Fri, Jun 13 2008 11:00:00 GMT

This action confirms the effective date of the direct final rule that establishes Class E airspace at Hinton, OK, published in the Federal Register March 26, 2008 (73 FR 15881), Docket No. FAA2008 0328, Airspace Docket No. 08ASW4.

Revision of Legal Descriptions of Multiple Federal Airways in the Vicinity of Farmington, NM

Fri, Jun 13 2008 11:00:00 GMT

This technical amendment corrects an error in the airspace description of a final rule published in the Federal Register on July 21, 2003 (68 FR 42962), Docket No. FAA200213013, Airspace Docket No. 02ANM10. In that rule, the description of Jet Route 10 (J10) was incorrect. This is an administrative correction to a published legal description. Additionally, the cite for J10 was incorrectly written as paragraph 6010(a) Domestic VOR Federal Airways: This will be corrected to ``paragraph 2006 Jet Routes''.

Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous

Fri, Jun 13 2008 11:00:00 GMT

This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

Airworthiness Directives; APEX Aircraft Model CAP 10 B Airplanes

Fri, Jun 13 2008 11:00:00 GMT

We are revising an earlier NPRM for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

An internal review evidenced that the flight controls tie rod bolts currently installed on the airplane are not in accordance with the design data. Indeed the bolt shank length has been determined too short and the material properties of the spacers have been found inadequate according to the prescribed torque value.

Therefore, bolts' threads could be subject to excessive wear, which might induce play in flight controls and consequently, induce vibrations in the control surfaces and reduce the airplane handling. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

Airworthiness Directives; DG Flugzeugbau GmbH Model DG-500MB Powered Sailplanes

Fri, Jun 13 2008 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

A DG500MB experienced, after the engine shutdown, an uncommanded retraction of its powerplant.

Investigations revealed that some bolts of the extension retraction mechanism had fractured because of fatigue stress due to increasing pushpull loads acting on incorrectly tightened screws.

This condition, if not corrected, could lead to damage of the propeller and the fuselage, thereby reducing the structural integrity of the sailplane.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

Airworthiness Directives; Lockheed Model 382, 382B, 382E, 382F, and 382G Series Airplanes

Fri, Jun 13 2008 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for all Lockheed Model 382, 382B, 382E, 382F, and 382G series airplanes. This proposed AD would require revising the FAAapproved maintenance program by incorporating new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This proposed AD would also require the accomplishment of certain fuel system modifications, the initial inspections of certain repetitive fuel system limitations to phase in those inspections, and repair if necessary. This proposed AD results from a design review of the fuel tank systems. We are proposing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
