What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) As reported by Moline ATCT, on April 5, 2005, mesaba flight #3637 reported a number one engine fire warning illuminated after departure at approximately 200' AGL. At approximately 500'-600' AGL the indication of a fire was no longer present. The aircraft landed without further incident. Examination by maintenance revealed the right hand (p/n 2-163-620-37) fuel manifold was leaking fuel, (see Honeywell SB72-1094). It appears the manifolds, part numbers 2-163-620-37 (RH) and 2-163-620-38 (LH), and their associated fuel nozzles installed as the closing action for AD 97-11-05, are losing torque after approximately 3000 cycles. This causes the manifold fuel nozzles to loosen during hi-power engine operation (take-off and climb) resulting in fuel spraying into the engine cowl. This fuel is ignited and the resulting fire caused the fire warning illumination. To date reducing engine power has extinguished the flames but the potential for a catastrophic event is evident.
As the FAA filed it
(-23) AS REPORTED BY MOLINE ATCT, ON APRIL 5, 2005, MESABA FLIGHT #3637 REPORTED A NUMBER ONE ENGINE FIRE WARNING ILLUMINATED AFTER DEPARTURE AT APPROXIMATELY 200' AGL. AT APPROXIMATELY 500'-600' AGL THE INDICATION OF A FIRE WAS NO LONGER PRESENT. THE AIRCRAFT LANDED WITHOUT FURTHER INCIDENT. EXAMINATION BY MAINTENANCE REVEALED THE RIGHT HAND (P/N 2-163-620-37) FUEL MANIFOLD WAS LEAKING FUEL, (SEE HONEYWELL SB72-1094). IT APPEARS THE MANIFOLDS, PART NUMBERS 2-163-620-37 (RH) AND 2-163-620-38 (LH), AND THEIR ASSOCIATED FUEL NOZZLES INSTALLED AS THE CLOSING ACTION FOR AD 97-11-05, ARE LOSING TORQUE AFTER APPROXIMATELY 3000 CYCLES. THIS CAUSES THE MANIFOLD FUEL NOZZLES TO LOOSEN DURING HI-POWER ENGINE OPERATION (TAKE-OFF AND CLIMB) RESULTING IN FUEL SPRAYING INTO THE ENGINE COWL. THIS FUEL IS IGNITED AND THE RESULTING FIRE CAUSED THE FIRE WARNING ILLUMINATION. TO DATE REDUCING ENGINE POWER HAS EXTINGUISHED THE FLAMES BUT THE POTENTIAL FOR A CATASTROPHIC EVENT IS EVIDENT.
