14 CFR 11.81(b) - Specific section from which relief is sought:

For Dassault Falcon 2000EX Easy, N57AL (S/N: 055); Dassault Falcon 2000LX, N157AL (S/N: 110);

Dassault Falcon 2000LX N257AL (S/N: 151); Dassault Falcon 2000LX, N741SP (S/N: 207), we request

relief from the following portion of 14 CFR:

§135.156, Amdt 135-120, Flight data recorders: filtered data

(d) Compliance. Compliance is required as follows:

(4) After April 21, 2014, no aircraft flight data recording system may filter any parameter

listed in paragraph (c) of this section that does not meet the requirements of Appendix D

or F of this part, unless the certificate holder possesses test and analysis procedures and

the test results that have been approved by the FAA. All records of tests, analysis and

procedures used to comply with this section must be maintained as part of the correlation

documentation required by § 135.152 (f)(1)(iii) or (f)(2)(iii) of this part as applicable.

14 CFR 11.81(c) - Extent and reason for seeking relief:

For Dassault Falcon 2000EX Easy, N57AL (S/N: 055); Dassault Falcon 2000LX, N157AL (S/N: 110);

Dassault Falcon 2000LX N257AL (S/N: 151); Dassault Falcon 2000LX, N741SP (S/N: 207), we are

requesting an exemption from compliance with the above listed portion of the flight data recorders.

Compliance with the regulations requires retrofit with EASy II upgraded avionics Load. Considering the

large amount of Falcon aircraft being retrofitted with EASy II upgraded avionics, there is a significant

waiting time before being accepted in a Service Center for retrofit. The amount of aircraft retrofitted

monthly is limited worldwide, by the large amount of equipments to supply. Finally, this retrofit requires a

significant downtime to adapt to scheduled maintenance checks in a way to maintain reasonable

operational use of our aircraft. After review, we plan to retrofit our aircraft with EASY II upgraded

avionics and have been given the following date by Honeywell (the manufacturer of the upgraded

avionics) N257AL - July 2014, N157AL - September 2014, N57AL - October 2014 and N741SP -

January 2015.

14 CFR 11.81(d) - Public interest / benefit:

Being unable to operate N57AL, N157AL, N257AL and N741SP would have a significant economic

burden on us. Denial of this petition would not be in the public's interest and would significantly reduce

the operational capability of the affected aircraft, relegating these business aircraft to a state of reduced

capability: indeed, Flight Data Recorder removal of data filtering is covered in EASy II global avionics

upgrade offering others functionalities such ADS-B Out, FANS1A, ATNB1 or LPV.

For the period in which the exemption would be in effect, there would not have any safety degradation.
14 CFR 11.81(e) - Information supporting this petition:

This petition for exemption is related to the Flight Data recorder: data filtering to be removed, as

mandated by 14 CFR §§135.156 Amendment 135-120. This exemption, if granted, would allow us to

benefit from the commercial use of Dassault Falcon 2000EX Easy, N57AL (S/N: 055); Dassault Falcon

2000LX, N157AL (S/N: 110); Dassault Falcon 2000LX N257AL (S/N: 151); Dassault Falcon 2000LX,

N741SP (S/N: 207) between April, 21, 2014 and the retrofit dates noted above.

If this petition is denied, then commercial flight operations of Dassault Falcon 2000EX Easy, N57AL

(S/N: 055); Dassault Falcon 2000LX, N157AL (S/N: 110); Dassault Falcon 2000LX N257AL (S/N: 151);

Dassault Falcon 2000LX, N741SP (S/N: 207)will have to be interrupted until EASy II upgraded avionics

retrofit is applied.

Granting this exemption would not affect nor degrade the inherent safety of the airplane. This

exemption deals only with the recording of pitch control surface position (parameter 15), lateral

control surface position (parameter 16), yaw control surface position (parameter 17) and

cockpit flight control input forces (parameter 88); it therefore has no impact on operational safety.
