Contributing to the accident were (1) deficiencies in Learjet’s design of and the Federal Aviation Administration’s (FAA) certification of the Learjet Model 60’s thrust reverser system, which permitted the failure of critical systems in the wheel well area to result in uncommanded forward thrust that increased the severity of the accident; (2) the inadequacy of Learjet’s safety analysis and the FAA’s review of it, which failed to detect and correct the thrust reverser and wheel well design deficiencies after a 2001 uncommanded forward thrust accident; (3) inadequate industry training standards for flight crews in tire failure scenarios; and (4) the flight crew’s poor crew resource management (CRM). ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Landing gear system: tire casing](https://openairdocs.org/ntsb-findings/01023244): Aircraft › Aircraft systems · Incorrect service/maintenance (probable cause);
