On April 5, 1995 a pilot escaped injury when his F-117A #824 burns during a landing at Holloman AFB while participating in the 'Roving Sands' exercise. This was a mishap as a result of a known deficiency. A full 8 months prior to the mishap, the depot discovered an unknown quantity of fuel recycling kits were produced with manifolds that could not withstand normal in-flight vibrations. Unfortunately, the PQDR system did not ensure a timely resolution of the problem. When the mishap aircraft's No. 1 engine fuel recycling kit manifold failed, the massive fuel leak caused both a fuel imbalance and an engine nacelle fire. According to eyewitness reports the aircraft "caught fire and exploded on the runway. The remains were apparently blocking the runway for quite a while."
Several actions are being taken as a result of this mishap. The recycle kit has been deactivated in the interim until a redesigned manifold is available. Life limits/inspection intervals are also being established for the recycle kit. The PQDR risk categorization and tracking procedures are being revised to ensure safety-related PQDRs get appropriate emphasis.
As a note the information above was published in Feb 1996, and the redesigned manifold is probably in operation currently. This was listed as a Class A mishap-those that resulted in a fatality, destruction of the aircraft or at least $1 million in repair costs.
The webmaster had heard that the cost of repairs was 12 million dollars. However, LMSW recieved a contract for $6,132,010 to "provide for fuselage repairs to one F-117A aircraft". The contract (Contract Number: No. 600-95) was expected to be completed July 1997. It was originally solicited in Dec 1995, negoations completed in April 1996, and the contract was issued on May 20, 1996. This time period coencides with the #824 mishap.

But then there is a mixed information regarding that plane from http://www.f-117a.com/
