Re: Supplement to Petition of Aerolineas Ejecutivas, S.A. de C.V. (Certificate No.

ER2F804F) for an Exemption from 14 C.F.R. § 129.5(b) (requirement to conduct

operations in accordance with the flight data recorder Standards of Annex 6 to

the Convention on International Civil Aviation); Docket FAA-2012-1256

Dear Sir/Madam:

Aerolineas Ejecutivas, S.A. de C.V. (ALE), hereby supplements its Petition for an

Exemption from from 14 C.F.R. § 129.5(b) filed in the above docket on November 23,

2012, with an English translation of the complete DGAC Policy Memorandum CP AV06/06 R1, dated December 20, 2006, entitled “Flight Data Recorder Specifications.” A

Spanish copy of the Policy Memorandum, with an English translation of relevant

excerpts, was attached to ALE’s initial Petition.

The complete English translation provides additional support for ALE’s Petition.

The “Background” and “Description” sections on pages 2 and 3 and Section 2.8.1.3 on

page 11 of the Memorandum state that the DGAC has modified its enforcement policy

regarding flight data recorder (FDR) requirements for aircraft that weigh more than

5,700 kg (12,540 pounds) but have nine or fewer seats. The Memorandum explains

that the DGAC is not enforcing the FDR requirement for such aircraft due to the fact

that supplemental type certificates are generally not available for the installation of

FDRs on such aircraft.

For these reasons and the reasons set forth in its initial Petition, ALE hereby

respectfully requests an exemption from Part 129.5(b) to the extent Annex 6 to the

International Civil Aviation Convention may require ALE to install flight data recorders in

its aircraft configured for nine or fewer passenger seats.

Respectfully submitted,

Objective. 

This Poliey Memorandum aims lo establish Ihe polieies for the use of flight data 

reeorders (FDR) and for the reeording duration of eoekpit voiee reeorders (CVR). lo 

complement the Offieial Mexican Norm NOM-022-SCT3-2001, speeifying the 

technical requirements for this equipmenl.. 

Legal Basis. 

Thls Policy Memorandum is based on Ihe Articles 6 (Sections " 111, XI, and XV) and 

32 of the Civil Aviation Law (Ley de Aviación Civil); and 127 of its Regulations, as 

wel/ as Official Mexlcan Norms NOM-011-SCT3-2001 and NOM-022-SCT3-2001. 

Procedures. 

This Policy Memorandum complements the guidelines and policies to be fol/owed 

for the instal/ation and use of flight data recorders and the recording duration of 

coekpit voice reeorders of aircraft referred lo in the "applieability" paragraph, as a 

complementary part of the Official Mexican Norm NOM-022-SCT3-2001 and 

notification of which shal/ be given by the airport authorities. 

Appllcability . 

This Policy Memorandum applies to al/ civil and government (non-military) aircraft, 

fixed-wing or rotorcraft, as described herein, in regards the Official Mexican Norm 

NOM-022-SCT3-2001, belonging to or in the possession of concessionaires, 

license holders and foreign air operator who fly or intend lo fly in Mexican airspace. 

Policy Statement. 

Background. 

The Official Mexican Norm NOM-022-SCT3-2001 and its Amendment were 

published in the Federal Offieial Gazette on January 21, 2002 and on January 4, 

2004, entering into force on March 22, 2002 and on January 5, 2004, respectively. 

The Omeial Mexican Norm establishes the instal/ation speeifications for the flight 

data recorders for fixed-wing aircraft with a maximum certified takeoff mas s in 

excess of 5,700 kilograms, while for rotorcraft the specifications are applicable for 

those wilh a maximum certified takeoff mass in excess of 7,000 kilograms. Also, the 

Officlal Mexican Norm establishes, in point 5.18, the required time extensions to

CP AV-OS/OS R1 

FL/GHT DATA RECORDER SPECIFICA TIONS 

meet the specifications for cockpit voice recorders, and the Amendment granted an 

extension until January 5, 2006, for these specifications to be me!. However, during 

the period of application of the Official Mexican Norm, some complications have 

arisen that have prevented some aircraft from being able to meet the established 

specifications: thorough engineering studies are required for the installation of flight 

data recorders, and these must include calculations, test reporls, electrical 

installation diagrams or designs, structural and electromagnetic compatibility 

analyses. These ensure that the equipment's installation will not affect the aircraft's 

airworlhiness. As the aircraft's original design is affected, a specific approval is 

required for each modification, for each type of individual aircraft. The approval of 

the modification may be obtained through a Supplemental Type Cerlificate (STC) 

issued by a foreign aviation authority and validated by the DGAC in Mexico, or 

through an engineering study, carried out in compliance with the Official Mexican 

Norm NOM-021/3-SCT3-2001. 

The main obstacles have been found with aircraft that carry 9 passengers or fewer. 

Many such aircraft weigh over the 5,700 kilograms required by the Official Mexican 

Norm and where STC modifications are unavailable globally, and where an 

engineering study would be unaffordable. 

One of the main reasons why STCs do not exist on the market is because the 

specifications established by some foreign aviation authorities, such as the United 

States' FM, only require the use of flight data recorders tor aircraft that carry 10 

passengers or more. 

Furlhermore, in regards the types of flight data recorders, the International Civil 

Aviation Organization (ICAO) has revised and established new types that are in line 

with current aerospace technology, and it has also revised the specifications and 

altered the obligations for the duration of recordings from cockpit voice recorders of 

two hours for fixed-wing aircraft with a maximum cerlified takeoff mass in excess of 

5,700 kilograms, and helicopters, regardless of their weight, which were 

manufactured after January 1, 2003, instead of January 1, 1990, as originally 

specified. 

Descrlption. 

The installation and use of flight data recorders on aircraft that operate in Mexican 

airspace, as well as their specifications, shall be subject to the stipulations in 

Official Mexican Norm NOM-022-SCT3-2001 and its Amendment; however, in order 

tor the installation specifications ot the flight data recorders (FDR) to be consistent 

with the availability of current STCs in the industry, for passenger aircraft, and with 

the ICAO requirements for the type of recorder, the tollowing establishes the policy 

to be followed by the Aviation Authority, to en force its application. It also 

establishes the policy of the duration of recordings of the cockpit voice recorders for 

aircraft manufactured after January 1, 2003, to make them compatible with the 

ICAO specifications on the duration of recordings.
