Drop Test - Cessna Golden Eagle 421B

This report presents the results of two airplane vertical impact tests conducted at the Federal Aviation Administration FAA Technical Center, Atlantic City International Airport, New Jersey. These tests entailed dropping a low wing, twin engine Cessna 421B aircraft from a vertical height of 11.2 feet, resulting in an impact velocity of approximately 26.0 feet per second fts. In both tests the aircraft was configured to simulate actual in-flight conditions including seats, occupants, and fuel. The structural response of the airframe, seats, and simulated occupants anthropomorphic dummies were measured throughout the tests, and the results are presented in this report. The data collected in these tests and future tests of other commuter type aircraft will provide the basis for improved seat standards for commuter airplanes. These tests describe the impact response characteristics of commuter category airplane airframes, floor structures, seats, seat attachments and occupant restraint systems.
