AD 2018-11-10

We are superseding Airworthiness Directive (AD) 2017-01-07, which applied to all Dassault Aviation Model FAN JET FALCON airplanes; Model FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE- FALCON 200 airplanes; Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20- F5 airplanes; and Model MYSTERE-FALCON 50 airplanes. AD 2017-01-07 required a functional test or check of the main entry door closure and warning system, and applicable door closing inspections, adjustments, operational tests, and corrective actions if necessary. This AD requires repetitive door closing inspections, adjustments, operational tests, and corrective actions if necessary. This AD was prompted by a report indicating that during approach for landing, the main entry door detached from an airplane. We are issuing this AD to address the unsafe condition on these products.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2017-01-07, Amendment 39-18774 (82 FR 1595, January 6, 2017), and adding the following new AD:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2017-01-07, Amendment 39-18774 (82 FR 1595, January 6, 2017) (``AD 2017-01-07''). AD 2017-01-07 applied to all Dassault Aviation Model FAN JET FALCON airplanes; Model FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 200 airplanes; Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes; and Model MYSTERE-FALCON 50 airplanes. The NPRM published in the Federal Register on March 1, 2018 (83 FR 8807). The NPRM was prompted by a report indicating that during approach for landing, the main entry door detached from the airplane. The NPRM proposed to continue to require a functional test or check of the main entry door closure and warning system, and applicable door closing inspections, adjustments, operational tests, and corrective actions if necessary. The NPRM also proposed to require repetitive door closing inspections, adjustments, operational tests, and corrective actions if necessary. We are issuing this AD to detect and correct defective crew/passenger doors. Such a condition could result in the in-flight opening or detachment of the crew/passenger door, which could result in loss of control of the airplane and injury to persons on the ground.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017-0123, dated July 20, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Dassault Aviation Model FAN JET FALCON airplanes; Model FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 200 airplanes; Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes; and Model MYSTERE-FALCON 50 airplanes. The MCAI states:

During approach for landing, at an altitude of 7,000 feet, a MF20-D5 lost the main entry door (MED). The flight crew maintained control of the aeroplane to land uneventfully. The results of the preliminary technical investigations concluded that the cause of this event could be either a broken cable, or an unlocked safety catch, associated with one or two deficient micro switches.
This condition, if not detected and corrected, could lead to in- flight opening and/or detachment of the MED, possibly resulting in loss of control of the aeroplane, and/or injury to persons on the ground.
To address this potential unsafe condition, Dassault issued Service Bulletin (SB) F20-789, SB F200-133 and SB MF50-531, providing instructions for inspection/adjustment, and an operational test of the MED closure. Consequently, EASA issued AD 2015-0007 [which corresponds to FAA AD 2017-01-07] to require a one-time accomplishment of a functional test/check of the MED closure/warning system. It also required [a general visual] inspection and operational test of the MED [including the control andlatching mechanisms] and, depending on findings, accomplishment of applicable corrective action(s).
Since that [EASA] AD was issued, EASA determined that the inspection and operational test of the MED must be repeated to ensure continued safety.
For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2015-0007, which is superseded, and additionally requires repetitive inspections and operational tests of the MED.

Corrective actions include adjusting the telescopic rod bolts on the door until the clearance between the lower part of the door and the fuselage is within the specified tolerances. The corrective actions for the control and latching mechanisms include adjusting components and replacing damaged components (including pull latches, microswitches, pulleys, and cables). Signs of damage include cracks, corrosion, wear, and distortion. You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for andlocating Docket No. FAA-2018-0117.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or

[[Page 25557]]

on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.

This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

Costs of Compliance

We estimate that this AD affects 392 airplanes of U.S. registry. We estimate the following costs to comply with this AD:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspections/adjustments/4 work-hours x $85 $0 $340................ $133,280.

We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ``General requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division.Regulatory Findings

We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
1. Is not a ``significant regulatory action'' under Executive Order 12866;
2. Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in Alaska; and
4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
