Airframe is a novel by the American writer Michael Crichton, his eleventh under his own name and twenty-first overall, first published in 1996, in hardcover, by Knopf and then in 1997, as a paperback, by Ballantine Books. The plot follows Casey Singleton, a quality assurance vice president at the fictional aerospace manufacturer Norton Aircraft, as she investigates an in-flight accident aboard a Norton-manufactured airliner that leaves three passengers dead and 56 injured.
Airframe remains one of Crichton's few novels not adapted to film. Crichton stated this was due to the great expense needed to make such a film. The novel's dense technical details for the accident investigation may also have hindered cinematic adaptations.
Plot summary
Over the Pacific Ocean, TransPacific Airlines Flight 545 experiences severe pitch oscillations, leading to dozens of injured passengers and several deaths. The plane, a Norton Aircraft N-22, has an excellent safety record, and the captain is highly skilled, making the possibility of human error unlikely. Casey Singleton, a vice president in quality assurance at Norton, is assigned by COO John Marder to the Incident Review Team (IRT) to investigate. The IRT has one week to identify the issue in order to prevent a major sale with China from falling apart over safety concerns.
Due to issues with the flight recorders, the team is forced to manually check each system of the aircraft. At first, all signs point to the plane's slats accidentally deploying mid-flight. Though other N-22s had exhibited similar slats errors in the past, Norton assumed the problem had been fixed. Their search uncovers a counterfeit part in the wing, but this would not have been enough to cause the accident on its own. Meanwhile, Casey grows suspicious of Bob Richman, an arrogant Norton family member assigned to assist her. Additionally, the factory union is concerned the China sale will offset the wing to China, threatening employees' jobs, and the union seeks to sabotage the deal.
An unrelated N-22 engine failure and the release of passenger camera footage from Flight 545 draws heavy media attention to Norton. Jennifer Malone, a producer for the news program Newsline, is interested in reporting on Norton's flaws and pursues the story; Marder asks Casey to conduct an interview for Newsline. Later, Casey realizes the plane was equipped with a Quick Access Recorder (QAR) – the team did not know the plane was equipped with one because QARs are optional. Casey locates the QAR and pieces together the events that caused the accident. First, the counterfeit part caused a sensor in the plane's wing to malfunction, which produced an error message in the cockpit. This error message could be cleared by deploying and retracting the plane's slats. Although deploying the slats would change the shape of the wing, the N-22's autopilot could adjust without incident. However, the pilot at the time of the accident was the captain's son, who was not certified to fly the N-22; he manually overcorrected, overriding the autopilot and sending the plane into a series of oscillations.
Casey realizes she cannot publicize this information. Publicly pinning the blame for the accident on a TransPacific employee would sour relations with the airline, ruining future sales just as surely as any N-22 safety issues would. During her Newsline interview, she also discovers Richman has set her up to fail as part of a larger conspiracy. Richman and Marder had secretly prepared a larger sale to a South Korean airline, which included offsetting the wing. They hoped to use the accident to sink the China deal and oust CEO Harold Edgarton, confident that the accident would not jeopardize the Korean deal.
Casey thwarts the plan by allowing Malone onto a test flight for the N-22 from the accident, where it is shown a slats deployment alone would not cause the accident. Once Malone is shown the evidence, she cannot air her segment as planned without opening up Newsline to a defamation lawsuit. She is also unable to report the true story, since her boss thinks it is not exciting enough to hold people's attention. With the N-22's reputation cleared, the China deal goes off without a hitch. Afterwards, Edgarton promotes Casey to head the company's Media Relations Division. Richman is arrested in Singapore for narcotics possession, while Marder leaves the company, supposedly on good terms.
