Airworthiness Directive · Amendment 39-15573 · Electrical power
Dassault Model Falcon 7X Airplanes
This AD applies to Dassault Model Falcon 7X airplanes, all serial numbers, certificated in any category, if equipped with secondary power distribution box (SPDB) units with part number (P/N) SPD500-B3, SPD600-A9, SPD300-B3-A6 and/or SPD400-B4-A6, except those airplanes that have received modification M890 prior to delivery.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) Within 10 days after the effective date of this AD, revise the Limitations Section of the AFM to include the following information. This may be done by inserting a copy of this AD in the AFM. These temporary amendments take precedence over the same procedures displayed through the electronic check list (ECL) in the aircraft.
“○ Dispatch with ATA27 Flight Controls MMEL items is not authorized.
○ Dispatch with IRS 3 inoperative is not authorized.
○ Land as soon as possible upon display on Crew Alerting system of following messages per the AFM as already requested for ELEC: LH FRONT ESS FAIL (AFM 3-190-50):
• ELEC: LH REAR ESS FAIL (AFM 3-190-50)
• ELEC: RH FRONT ESS FAIL (AFM 3-190-55)
• ELEC: RH REAR ESS FAIL (AFM 3-190-55)”
Note 1: When a statement identical to that in paragraph (f)(1) of this AD has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed from the AFM.
(2) Within 2 months after the effective date of this AD, replace all SPDB units with upgraded units in accordance with the Accomplishment Instructions of Dassault Service Bulletin 7X-064, dated April 16, 2008. After replacement of all SPDB units as required by paragraph (f)(2) of this AD, the limitations required by paragraph (f)(1) of this AD may be removed from the AFM.
Note 2: This AD differs from the MCAI and/or service information as follows: Although the MCAI specifies to amend the Abnormal Procedures section of the AFM, the Quick Reference Handbook 2, and the Master Minimum Equipment List, this AD instead requires revising only the Limitations section of the AFM. Operators must comply with the terms of the Limitations section, as specified in section 91.9 of the Federal Aviation Regulations (14 CFR 91.9).
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.
