eastern airlines flight 304

Once the upset occurred, it was not possible to trim the horizontal stabilizer back to the nose-up position, because of the severe G-forces generated by the crew's pulling back on the yoke after the upset.[3]. Detailed examination of all structure recovered revealed no evidence of in-flight fire, explosion, or structural failure. Other factors could also prolong the dive. At 0203.15 the crew replied, "OK." This was the last transmission received from the flight. Two discrepancies involved yaw, six referred to longitudinal control problems, and three reported automatic disconnects. This ​setting is equivalent to the stabilizer being in the full AND position. Their reported dated May 29, 1964, indicated that while full stabilizer trim capability existed, a comparable wear pattern was reproduced on the test assembly. ​By presuming an acceleration after takeoff to speeds where stick forces against a jammed AND stabilizer would become noticeable and further hypothesizing some continued acceleration while trying to reactivate the stabilizer, say to 260 or 270 knots, one can account for the speed element necessary to place the aircraft near the region of the accident. The radar target was identified five miles north of the New Orleans VORTAC, and a radar handoff was effected at 0202.38. Now a new set of factors comes into play, several of which are quite basic while others are more subtle and involved. The review of the aircraft records disclosed a recent history of PTC difficulties. The bariton bar at this time started to stabilize and showed us coming back through 90 degrees vertical to a level attitude laterally. He stated that "…we encountered the most violent jolt I have ever experienced in over 20,000 hours of flying. The first fuselage bending frequency is 3.78 c. p. s. During the investigation the Board discovered several incidents of misrigging in the longitudinal control systems of other DC-8 aircraft, including some from other airlines. The Board has devoted the last several pages to a discussion of a set of circumstances and a possible causal area largely unprovable. Furthermore, if the indicator system failed, as occurred on the leased aircraft and on this one earlier in the day preceding the accident, it is also possible that the PTC actuator could have become inoperative at any position. On the other hand a retracted, inoperative PTC would have no effect at lower speeds but would. Since the aircraft was found 6.5 miles northeast of this position, it is obvious that there was a time lapse between this observation and his inquiry about the flight as 0205:40. Discovery of the wreckage was finally confirmed late in the afternoon, March 13. However likely or remote the possibility, the Board found it difficult to conclude that this condition alone, PTC extension, and AND stabilizer, could precipitate the complete loss of longitudinal control so obviously manifested by the condition of the wreckage. [13] To the pilot the aircraft responds the same, whether or not it was required to meet any stability criteria for the condition in which he finds himself. We were now on instruments with no Visual reference and continued with severe to violent buffeting, ripping, tearing, tending crashing sounds. No inspection of the actuator position or operating capability of the indicator system was made. For 213,000 pounds, c. g. at 26 percent and KCT. We reduced power shortly thereafter and maintained this approximate speed until breaking out on top." As stated before, the possibility exists that the PTC actuator was extended. Simultaneous operation of any set of dual switches or handles is required to actuate the system. Statements were obtained from 29 witnesses, 14 of whom were located on the north shore of the lake, closest to the crash site. This condition while it could worsen the situation, is not a necessary prerequisite to a PIO situation. A Notice to Airmen advised that the VOR position of the New Orleans VORTAC was inoperative from 2259 to 0458. The Board determines the probable cause of this accident was the degradation of aircraft stability characteristics in turbulence, because of abnormal longitudinal trim component positions. It should be noted that none of these factors in itself constitutes a hazard or even a serious situation, however, several or all of them in combination could create conditions under which control of the aircraft could be lost, partially or completely.
