The Bell 407 is a four-blade, single-engine, civil utility helicopter. A derivative of the Bell 206L-4 LongRanger, the 407 uses the four-blade, soft-in-plane design rotor with composite hub developed for the United States Army's OH-58D Kiowa Warrior instead of the two-blade, semi-rigid, teetering rotor of the 206L-4.

Design and development

File:CBOSS Bell 407.jpg 2008]]

In 1993, Bell began the development of the New Light Aircraft as a replacement for its Model 206 series. The program resulted in the 407, a development of Bell's LongRanger.Frawley, Gerard. The International Directory of Civil Aircraft, 2003-2004, p. 47. Aerospace Publications Pty Ltd, 2003. {{ISBN|1-875671-58-7}}. A 206L-3 LongRanger was modified to serve as the 407 demonstrator. The demonstrator used hardware for the 407 and added molded fairings to represent the 407's wider fuselage then under development.

The demonstrator was first flown in 1994, and the 407 program was publicly announced at the Heli-Expo in Las Vegas, Nevada, in January 1995.{{cite web|url= http://www.flightglobal.com/news/articles/bell-launches-model-407-22595/bell-launches-model-407.html|title=Bell launches Model 407|access-date= 9 April 2023|author= |last= |first= |author-link= |work= Flight International|date= February 8, 1995 |archive-url= https://web.archive.org/web/20121114154301/http://www.flightglobal.com/news/articles/bell-launches-model-407-22595/|archive-date= November 14, 2012|url-status= dead}} The first 407 prototype (C-GFOS) accomplished its maiden flight on June 29, 1995, and the second prototype (C-FORS) followed on July 13, 1995. After a short development program, the first production 407 (C-FWQY/N407BT) flew on November 10, 1995.

The Bell 407 features the four-blade main rotor developed for the OH-58D (Model 406). The blades and hub use composite construction without life limits, and provide better performance and a more comfortable ride. The 407's fuselage is {{convert|8|in|cm}} wider, increasing internal cabin space, and includes 35% larger main cabin windows. The more powerful Rolls-Royce/Allison 250-C47 turboshaft allows an increase in Maximum Takeoff Weight and improves performance at hotter temperatures and/or higher altitudes. The helicopter has standard seating for two crew and five cabin seats."Bell 407". Jane's Helicopter Markets and Systems. Couldson, Surrey, UK: Jane's Information Group, 2010.

The 407 was certificated by Transport Canada on February 9, 1996, with the FAA following shortly after on February 23.[http://www.flug-revue.rotor.com/frtypen/FRB407.htm "Bell Helicopter 407"] {{webarchive |url=https://web.archive.org/web/20100203181337/http://www.flug-revue.rotor.com/frtypen/FRB407.htm |date=February 3, 2010 }}. Flug Revue, March 19, 2001. Full production began in 1996 at Bell's Mirabel, Quebec, Canada plant and produced 140 airframes in 1997, to fill the initial orders.

In 1995, Bell tested a shrouded tail rotor on the 407, but did not proceed with it. For a time, Bell studied developing the Model 407T twin-engine variant, but instead chose to develop the essentially all-new twin-PW206D powered Bell 427.

Bell began deliveries of the 407 in 1996. The 1,000th helicopter was delivered on June 15, 2010. 1,400+ by Dec 2017, and over 1600 were produced by early 2023.{{Cite web |last=Huber |first=Mark |title=Life Flight Network Adds Four Bell 407GXi Helicopters {{!}} AIN |url=https://www.ainonline.com/aviation-news/business-aviation/2023-02-06/life-flight-network-adds-four-bell-407gxi-helicopters |access-date=2024-05-04 |website=Aviation International News}}

The Bell 417 was a growth variant of the Bell 407, in essence a civil version of the Bell ARH-70.

File:Bell 407 GX Cockpit in 2011.jpg

On March 4, 2013, Bell unveiled a new armed version of the Bell 407GX, named the 407GT. It incorporates the Garmin G1000HTM flight deck to easily provide flight information. It can include infrared cameras, various armaments, and equipment to perform different missions such as armed transport, search-and-rescue, reconnaissance, and medical evacuation. The GT version uses the Universal Weapons Pylon, derived from the Bell OH-58 Kiowa, to carry different weapons including machine guns, rockets, and anti-armor missiles.[http://www.bellhelicopter.com/en_US/News/PressReleases/NewsRelease/NewsRelease.html?ReleaseID=1792180 "Bell Helicopter Introduces Increased Mission Capability with the Bell 407GT"] {{webarchive|url=https://web.archive.org/web/20130315134602/http://www.bellhelicopter.com/en_US/News/PressReleases/NewsRelease/NewsRelease.html?ReleaseID=1792180 |date=2013-03-15 }}.

Operational history

Bell made delivery of the first production 407 at Heli-Expo, in Dallas, Texas in February 1996. Launch customers for the aircraft were Petroleum Helicopters International (PHI), Niagara Helicopters, and Greenland Air.[http://www.bellhelicopter.com/en/aircraft/commercial/bell407_extras.cfm "History of the Bell Helicopter 407"] Bell Helicopter. {{webarchive |url=https://web.archive.org/web/20100922194027/http://www.bellhelicopter.com/en/aircraft/commercial/bell407_extras.cfm |date=September 22, 2010}}.

On 23 May 2007, Colin Bodill and Jennifer Murray completed a record pole-to-pole around the world flight using a standard Bell 407. The flight originated from Bell's facility at the Fort Worth Alliance Airport on December 5, 2006. The team flew about {{convert|36000|mi|km|sigfig=2}} over 189 days and 300 flight hours, through 34 countries. The project, named Polar First, was performed in partnership with the Royal Geographical Society to provide educational outreach to 28 international schools, which were visited during the trip. The project also served as a fundraiser for the SOS Children's Villages.{{cite magazine |title=Polar First Sets World Record |magazine=Rotorbreeze |date=July 2007}}

Accidents

On June 4, 2022, Bell 407 GXP, N98ZA, was substantially damaged in an accident near Fairfield, New Jersey. The commercial pilot was seriously injured. Investigation by the US National Transportation Safety Board (NTSB) found that the tail rotor crosshead drive plate was not bolted to the tail rotor crosshead. The tail rotor had been installed the day before; it was suspected that the bolts were not properly torqued.[https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/105184/pdf "NTSB preliminary report for accident number ERA22FA257"]. NTSB

On June 8, 2022 a Bell 407 had an inflight separation of its tail boom while in cruise flight near Kalea, Hawaii. The pilot and two passengers sustained serious injuries, while three other passengers had minor injuries. The helicopter was substantially damaged during the crash. The US NTSB determined that the upper-left tail boom attachment hardware was not installed, leaving only three of four attachment points connected. Wreckage markings indicated that the bolt had been present at one point but had fallen out, resulting in progressive fatigue cracking. The NTSB requested immediate action from the US FAA and Transport Canada in the form of an urgent airworthiness directive.{{cite web|url= https://www.ntsb.gov/investigations/AccidentReports/Reports/AIR2210.pdf|title= Require Immediate Inspection of Bell 407 Tail Boom Attachment Hardware and Fittings|access-date= 6 December 2022|author= NTSB|author-link= National Transportation Safety Board|work= ntsb.gov|date= 1 December 2022|archive-url= https://web.archive.org/web/20221203052204/https://www.ntsb.gov/investigations/AccidentReports/Reports/AIR2210.pdf|archive-date= 3 December 2022|url-status= live}}{{cite web|url= https://www.avweb.com/flight-safety/accidents-ntsb/ntsb-recommends-immediate-bell-407-inspections/|title= NTSB Recommends Immediate Bell 407 Inspections|access-date= 6 December 2022|last= O'Connor|first= Kate|work= AVweb|date= 5 December 2022 |archive-url= https://archive.today/20221206130913/https://www.avweb.com/flight-safety/accidents-ntsb/ntsb-recommends-immediate-bell-407-inspections/|archive-date= 6 December 2022|url-status= live}}
