Link Date Description
Factual Report (PDF) 4/19/99 NTSB "Factual" report on crash of Sky Warriors T-34 N140SW in Rydal GA. 4/19/99 is the date of the crash, not the date of the report. See bottom of this page for Probable Cause Report dated 11/2/2005.
A-99-47-50 (PDF) 5/28/99 NTSB Safety Recommendation to the FAA following crash of SW T-34 in May 1999.
A-99-047 (PDF) 12/1/99 FAA's response to NTSB recommendations. Part 1.
A-99-048 (PDF) 12/1/99 FAA's response to NTSB recommendations. Part 2.
A-99-049 (PDF) 12/1/99 FAA's response to NTSB recommendations. Part 3.
A-99-050 (PDF) 12/1/99 FAA's response to NTSB recommendations. Part 4.
FAA AD 2000-13-18 (31KB PDF) 6/22/01 FAA Airworthiness Directive (AD) 99-12-02. It places flight and operating limitations on Raytheon Aircraft Corporation (Raytheon) Beech Models 45 (YT-34), A45 (T-34A, B-45), and D45 (T-34B) airplanes. AD 99-12-02 resulted from a report of an in-flight separation of the right wing on a Raytheon Beech Model A45 (T-34A) airplane. The AD was issued as an interim action until the development of FAA-approved inspection procedures.

Raytheon has developed procedures to inspect the wing spar assemblies of the above-referenced airplanes. This AD requires repetitive inspections of the wing spar assembly for cracks with replacement of any wing spar assembly found cracked (unless the spar assembly has a crack indication in the filler strip where the direction of the crack is toward the outside edge of the filler strip).

This AD also includes a reporting requirement of the results of the initial inspection and maintains the flight and operating restrictions required by AD 99-12-02 until accomplishment of the initial inspection.

The actions specified by this AD are intended to prevent wing spar failure caused by fatigue cracks in the wing spar assemblies and ensure the operational safety of the above-referenced airplanes.

Raytheon SB 57-3329 (3MB PDF) 2/00 Raytheon Service Bulletin (SB) 57-3329, issued February 2000. Title: Inspection of Wing Spar Structure. This is a very large file -- 3 megabytes.
FAA SAIB CE-02-38R2 (42KB PDF) 8/7/02 FAA Special Airworthiness Information Bulletin CD-02-38R2 issued December 16, 2002, which replaces SAIB CE-02-38R1 issued August 7, 2002.

This revised SAIB advises owners of Beech Models 45 (YT-34), A45 (T-34A, B-45), and D45 (T-34B) airplanes of a means to extend the compliance time of AD 2001-13-18. It adds two alternatives to the Raytheon repetitive inspection procedure.

Probable Cause Report (Web) 11/2/05 NTSB Probable Cause Report on crash of N140SW. This report was originally released on 8/13/2001 but was revised on 11/2/05 -- more than six years after the accident -- for reasons we do not know at this time.
Brief of Accident (PDF) 11/2/05 Experienced NTSB report readers probably know exactly what this report is -- I'm a little fuzzy. The link on the page that pointed to is was labeled "Probable Cause" but it doesn't have nearly as much information as the web page version of the probable cause report -- see previous item.
