Airworthiness Directive · Amendment 39-15115 · Eclipse Aviation Corporation Model EA500 Airplanes
Eclipse Aviation Corporation Model EA500 Airplanes
Superseded. A later AD replaced this one: AD 2008-02-04. Comply with the one in force.
This AD applies to Model EA500 airplanes, serial numbers 000001 and up, that are certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Eclipse Aviation Corporation (Eclipse) Model EA500 airplanes. This AD requires you to incorporate information into the Limitations section of the airplane flight manual (AFM) that will require operation only in day visual flight rules (VFR), allow only a VFR flight plan, and maintain operation with two pilots. This AD is being issued because of three instances of loss of primary airspeed indication due to freezing condensation within the pitot system. The loss of air pressure in the pitot system could cause the stall warning to become unreliable and the stick pusher, overspeed warning, and autopilot to not function. The concern is heightened by the aerodynamic characteristics of the Eclipse Model EA500 airplane, which relies on the stall warning and the stick pusher to alert the pilot prior to the loss of aircraft control. The standby airspeed is reliable and not affected by this failure mode. A temporary AFM revision prohibits operation in instrument meteorological conditions (IMC), requires two pilots, and limits the airspeed and altitude envelope if the event occurs in flight. The AFM limitations and FAA operational rules allow Model EA500 flight crews to file an instrument flight rule (IFR) flight plan even though the airplane is not approved for flight in IMC. This potentially causes an undue workload burden and confusion when the pilot has to refuse any instructions that take them into IMC. We are issuing this AD to prevent an unsafe condition when Air Traffic Control's (ATC's) ability to maintain traffic separation is compromised because an airplane on an IFR flight plan cannot accept a flight plan into IMC.
To address this problem, before further flight after June 27, 2007 (the effective date of this AD), incorporate the following into the Limitations section of the AFM, unless already done:
“—Operate Only in Day Visual Flight Rules (VFR);
—File Only a VFR Flight Plan; and
—Operate with Two Pilots at All Times.”
(1) The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may insert the information into the AFM as specified in paragraph (e) of this AD.
(2) You may insert a copy of this AD into the Limitations section of the AFM to comply with this action.
(3) Make an entry into the aircraft records showing compliance with portion of the AD in accordance with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
