AD 2018-02-06

We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X, FALCON 2000EX, and FALCON 900EX airplanes. This AD requires revising the airplane flight manual (AFM) and minimum equipment list (MEL) to incorporate new limitations. This AD also provides an optional terminating action that removes the AFM and MEL limitations. This AD was prompted by a report indicating that, during approach, an airplane had an unexpected change of barometric settings on both the pilot and co-pilot sides, which also impacted certain display and navigational systems. We are issuing this AD to address the unsafe condition on these products.

Final rule; request for comments.

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.

This AD was prompted by a report indicating that, during approach, an airplane had an unexpected change of barometric settings on both the pilot and co-pilot sides, which also impacted certain display and navigational systems. We are issuing this AD to address unexpected changes to barometric settings, which could lead to an incorrect flight altitude and could ultimately adversely affect the airplane's continued safe flight and landing.

(f) Compliance

Comply with this AD within the compliance times specified, unless already done.

(g) Airplane Flight Manual (AFM) Revision

Within 10 flight cycles after the effective date of this AD, revise the Limitations Section of the Airplane Flight Manual (AFM) to include the statement specified in figure 1 to paragraph (g) of this AD. When a statement identical to that in figure 1 to paragraph (g) of this AD has been included in the limitations section of the general revisions of the AFM, the general revisions may be inserted into the AFM. [GRAPHIC] [TIFF OMITTED] TR19JA18.000

(h) Minimum Equipment List (MEL) Revision

Within 10 flight cycles after the effective date of this AD, revise the operator's MEL by incorporating the applicable information specified in figure 2 to paragraph (h) of this AD as a temporaryrestriction when dispatching the airplane with an inoperative traffic alert and collision avoidance system (TCAS) or enhanced ground proximity warning system (EGPWS). The MEL can be revised by inserting a copy of the applicable MMEL-CP page specified in figure 2 to paragraph (h) of this AD into the MEL. After revising the applicable MEL, dispatch of that airplane with an inoperative TCAS or EGWPS is allowed, provided that the applicable MEL for that airplane has been revised, as specified in the applicable dispatch restrictions specified in figure 2 to paragraph (h) of this AD.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017-0240, dated December 5, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Dassault Aviation Model FALCON 7X, FALCON 2000EX, and FALCON 900EX airplanes. The MCAI states:

An occurrence was reported where, during approach, a Dassault 7X aeroplane experienced an unexpected change of barometric setting values, on both pilot and co-pilot sides, also having some other effects on display and navigation systems. Investigation showed that a temporary defect of a Cursor Control Device (CCD) can release erroneous but apparently valid data to the avionics. Depending on the resulting flight deck effects, crew members may be unaware of any incorrect barometric setting values.
This condition, if not corrected, could lead to a wrong flight altitude, possibly affecting continued safe flight and landing.
To address this potential unsafe condition [Dassault Aviation] DA is developing corrective actions through an upgrade of ``EASy'' Avionics software. Pending the availability in service of these upgrades, DA issued an Aircraft Flight Manual (AFM) amendment and a Master Minimum Equipment List (MMEL) amendment, related to dispatch with a Traffic Collision Avoidance System (TCAS) or Enhanced Ground Proximity Warning System (EGPWS).
For the reasons described above, this [EASA] AD requires amendment of the applicable AFM and MMEL [and includes an optional terminating action].
This [EASA] AD is considered an interim measure and further AD action may follow.

Although the MCAI requires updating the MMEL, this AD requires revising the MEL. The MMEL is a master list of the minimum equipment with which the airplane can operate under given circumstances. A MEL is derivedfrom the MMEL and is tailored for individual operators. The optional terminating action is updating the aircraft avionics software to the latest EASy II version. You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-1250.

FAA's Determination and Requirements of This AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of these same type designs.

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because unexpected changes to barometric settings could lead to an incorrect flight altitude and ultimately adversely affect the airplane's continued safe flight and landing. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2017-1250; Product Identifier 2017-NM-174-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD based on those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receiveabout this AD.

Costs of Compliance

We estimate that this AD affects 320 airplanes of U.S. registry. We estimate the following costs to comply with this AD:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Updating the AFM/MEL............... 2 work-hours x $85 per hour $0 $170 $54,400
= $170. ----------------------------------------------------------------------------------------------------------------

Estimated Costs for Optional Actions ----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Software update............................ 8 work-hours x $85 per hour = $680. $0 $680 ----------------------------------------------------------------------------------------------------------------

According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all available costs in our cost estimate.

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

[[Page 2735]]

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.
