FAA Approval For ATG Javelin Requires Trial By Fire
As Aviation Technology Group works toward certification of its 500-knot, $2.795 million Javelin executive jet and military trainer aircraft, the FAA on Monday proposed special conditions regarding the aircraft's internally-mounted turbofans. The FAA believes "applicable [Part 23] airworthiness regulations do not contain adequate or appropriate safety standards" for two turbofans set side by side inside the fuselage and "not in the pilots' field of view." Central to the issue is fire suppression and specifically how one ill-fated engine's malaise (read: violent conflagration) would be isolated from the adjacent engine, fuel lines, a nearby 280-gallon fuel tank and primary structure and systems "passing through or near the engines" that support "critical flight controls." So far, the FAA is suggesting that the Javelin 100 be required to incorporate extinguishing along with fire detection systems and fire isolation. ATG told AVweb it is aware of the special conditions and is working closely with the FAA. "It is not uncommon for jets to have special conditions under Part 23. We don't expect any problems in certifying the Javelin," spokeswoman Sara Newton said. The FAA is seeking comments on the notice of proposed rulemaking by Feb. 7, 2007.
