AD 2015-08-02 Airworthiness Directives; Dassault Aviation Airplanes
Models named: MYSTERE-FALCON 50. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Dassault Aviation Model MYSTERE-FALCON 50 airplanes, certificated in any category, as identified in paragraphs (c)(1) and (c)(2) of this AD. (1) Airplanes with manufacturer serial numbers 5, 7, 27, 30, 34, 36, 78, 132, and 251 through 352 inclusive. (2) Airplanes with manufacturer serial numbers 2 through 250 inclusive, having Honeywell (formerly Allied Signal, Garrett AiResearch) TFE731-40-1C engines modified by Dassault Aviation Service Bulletin F50-280.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
This paragraph restates the requirements of paragraph (g) of AD 2015-02-04, Amendment 39-18071 (80 FR 5034, January 30, 2015), with no changes. Within 74 months after March 6, 2015 (the effective date of AD 2015-02-04), install two Rilsan protective plates between the glare shield electrical wiring and the engine fire pull handles, in accordance with the Accomplishment Instructions of Dassault Service Bulletin F50-530, dated November 12, 2013.
Unsafe condition
This AD was prompted by a report of an untimely and intermittent indication of slat activity due to chafing of the electrical wiring under the glare shield and behind the flight deck front panel, and also our determination that the published version of AD 2015-02-04, Amendment 39-18071 (80 FR 5034, January 30, 2015), incorrectly identified the AD number as “AD 2014-02-04.” We are issuing this AD to prevent chafing of the electrical wiring, which could result in a short circuit and generation of smoke in the cockpit, potential loss of several functions essential for safe flight, and consequent reduced controllability of the airplane.
Affected ADs
This AD replaces AD 2015-02-04, Amendment 39-18071 (80 FR 5034, January 30, 2015).
