The airplane prepared to depart at 9:40 pm EDT, lining up on runway 11 under night visual meteorological conditions. As it began its takeoff roll, the pilots realized that they had limited steering control and that the engine throttle levers could not be advanced to full power. The plane passed V1, the maximum speed at which the pilots could have aborted takeoff, but they failed to apply the brakes for about ten seconds or reduce the throttles for another four seconds after the crew realized there was a problem. The airplane rolled through the paved overrun area and across a grassy area, collided with approach lights and a localizer antenna, passed through the airport's perimeter fence, and came to a stop in a shallow ravine formed by the Shawsheen River, where its full load of fuel immediately caught fire. All seven people aboard were killed, and the airframe was destroyed by the impact and post-crash fire.September 9, 2015 Runway Overrun During Rejected Takeoff, Gulfstream Aerospace Corporation G-IV, N121JM, Bedford, Massachusetts, May 31, 2014 https://www.ntsb.gov/investigations/AccidentReports/Reports/AAR1503.pdf live https://web.archive.org/web/20210813205003/https://www.ntsb.gov/investigations/AccidentReports/Reports/AAR1503.pdf 13 August 2021 1 September 2021 National Transportation Safety Board NTSB/AAR-15/03 Investigation The National Transportation Safety Board (NTSB) issued its final report on 9 September 2015.

The gust lock handle also included an interlock mechanism intended to limit the throttle levers to just enough power for taxiing and idle while engaged. According to Gulfstream, this had been intended to prevent pilots from attempting to take off with the gust lock engaged. However, post-accident testing on other Gulfstream-IV airplanes found that, with the gust lock handle in the ON position, the forward throttle lever movement that could be achieved was three to four times greater than intended. The NTSB concluded that the probable cause of the accident was the flight crew's failure to perform the flight control check before takeoff,https://whyy.org/articles/pilot-error-caused-the-plane-crash-that-killed-lewis-katz/ NTSB: Pilot error led to the plane crash that killed Lewis Katz which led to their attempt to take off with the gust lock system engaged, and their delay in aborting the takeoff after they became aware that the controls were locked. The NTSB also cited as contributing factors the flight crew's habitual noncompliance with checklists, Gulfstream's failure to ensure that the Gulfstream-IV gust lock / throttle lever interlock system would prevent an attempted takeoff with the gust lock engaged, and the Federal Aviation Administration's failure to detect this defect during the Gulfstream IV's airworthiness certification.https://www.usatoday.com/story/news/2015/09/09/ntsb-bedford-crash-gulfstream-philadelphia-inquirer-lewis-katz/71922242/ NTSB: Pilots left wing controls locked in place in Gulfstream crash that killed 7 Bart Jansen USA TODAY Aftermath Following the accident, the FAA issued an Airworthiness Directive that gave operators three years to retrofit the gust lock systems on their Gulfstream-IV jets,https://news.aviation-safety.net/2017/08/02/faa-ad-gust-lock-modification-gulfstream-g-iv-jets-becomes-effective/ FAA AD on gust lock modification on Gulfstream G-IV jets becomes effective 2 August 2017 and Gulfstream immediately announced that it would redesign the gust lock system.https://www.forbes.com/sites/businessaviation/2015/10/02/gulfstream-responds-to-ntsb-report/ Business Aviation BrandVoice: Gulfstream Responds to NTSB Findings Tony Velocci Forbes The families of Katz and the pilots later filed wrongful-death lawsuits against the manufacturer.2016-03-21 Family of philanthropist Lewis Katz files wrongful death suit https://www.timesofisrael.com/family-of-philanthropist-lewis-katz-files-wrongful-death-suit/ live The Times of Israel https://web.archive.org/web/20160322211442/http://www.timesofisrael.com:80/family-of-philanthropist-lewis-katz-files-wrongful-death-suit/ 2016-03-22 0040-7909 References External links NTSB investigation docket Accident description at the Aviation Safety Network GokKYNOcp20 Official NTSB animated reconstruction of the accident sequence Category:Aviation accidents and incidents in Massachusetts Category:Aviation accidents and incidents in the United States in 2014 Category:Airliner accidents and incidents caused by pilot error Category:2014 in Massachusetts Category:Airliner accidents and incidents involving runway overruns Category:May 2014 in the United States
