Lawmakers from Colorado have asked federal aviation officials to ground a Mitsubishi-made aircraft involved in two fatal crashes in the state in nine months.
Three persons died in incidents in the state on Aug. 4 and Dec. 10 involving the Mitsubishi MU-2B-60.
"I am requesting that you immediately issue a directive to ground all [Mitsubishi MU-2B-60] aircraft until a thorough and complete investigation into its air worthiness can be determined," Rep. Tom Tancredo, Colorado Republican, wrote Aug. 4 to the Federal Aviation Administration.
The plane's manufacturer, Mitsubishi Heavy Industries America Inc., disputes claims that the aircraft is unsafe.
Sen. Ken Salazar, a Democrat, Rep. Bob Beauprez, a Republican, Rep. Diana DeGette, a Democrat, and Rep. Mark Udall, a Democrat, all from Colorado, also wrote FAA Administrator Marion C. Blakey and asked her to consider grounding the aircraft.
The FAA yesterday said it will re-evaluate the plane. As part of its inquiry, the FAA will examine the aircraft, operational procedures for the plane and pilot training.
An agency spokeswoman said it is too early to determine whether the FAA should ground the plane.
"We won't hesitate to do that if we have the data to support it," FAA spokeswoman Alison Duquette said.
The FAA re-evaluated Mitsubishi's MU-2B series of planes after 12 crashes and 16 fatalities in 1983 and 1984, but found no major problems with the aircraft. The agency re-evaluated the plane in 1996, after two more crashes, to investigate its performance in icy conditions and required changes in pilot training and a modification to the plane to improve safety.
It could take the FAA two months to complete its latest re-evaluation, Ms. Duquette said.
