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

For Falcon 900DX, N890BB (S/N 611) 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 Falcon 900DX, N890BB (S/N 611), 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

equipment’s 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 June 29, 2015.

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

Being unable to operate [our airplane(s)] 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 Falcon 900DX, N890BB (S/N611) between April, 21, 2014 and June 

29, 2015.

If this petition is denied, then commercial flight operations of [aircraft type & registration] 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.
