Ladies and Gentlemen; PETITION OF DELTA AIR LINES, INC. FOR AN EXEMPTION 

### February 25, 2016

In accordance with the Code of Federal Regulations, 14 CFR §11.81, Delta Air Lines 

### petitions for an exemption to 14 CFR § 

### 121.309(f)(2) 

### to the extent necessaryto locate the aft megaphone at door4-feft on Boeing 747 aircraft. Delta Air Lines has been operating underthe authority ofa similarexemption (6140) granted to Airlines for America (A4A) memberairlines for over 20 years. Section ofthe Federal Aviation Regulations Affected 14 CFR 

### § 121.309(1)(2); Megaphones Requested Relief Currently Delta is operating underthe authority of Exemption No. 6140 which provides relief, under certain conditions and limitations, from provisions of 14 CFR 

### § 121.309(f)(2) to the extent necessary to locate the aft megaphone at door4-left on Boeing 747 aircraft. As outlined in previous petitions on this matter, the Boeing 747 (B-747) aircraftwas certificated in accordance with 14 CFR §25 with the aft megaphone located at door4-left, instead ofdoor5-left, the most rearward door on the B-747. The B-747 has been in worldwide airline operation and Delta has been operating the aircraftfor more than 30 years, and the positioning ofthe aft megaphone at door4-left has proved to be an advantageous location in emergency evacuations. Repositioning the aft megaphonefrom its current position at door4-leftto the most aft position, door5-left, would not improvesafety butwould require Delta to expend resources unnecessarily.Petition for Exemption- 14 CFR 

### § 121.309(f)(2) Delta Air Lines, Inc. February 25, 2016 Page 2 

### Background The FAA has previously determined that thejustification forthe issuance of Exemption No. 6140, as valid and is in the public interest. The FAA Administrator has granted reliefthrough exemption to Airlines forAmerica from 14 CFR 

### § 121.309(f)(2} Delta Air Lines has been successfully operating the 6747-451 underthe relief authorized in Exemption 6140 for over 20 years. The only change to the reliefto which Delta requests is for an individual exemption be issued as Delta is no longera member ofA4A. 

### Requestfor expedited consideration Delta is also requesting that, as part ofthis Petition for Exemption request, the public comment phase be waived as perTitle 14 CFR Part 11.87(a}, which states: "The FAA maynotpublish a summary ofyourpetWon forexemption andrequest comments ifyoupresentor we findgoodcause why we shouldnotdelayaction on your petition. The factors we considerin deciding not to requestcommentinclude: (a) Whethergranting yourpetition wouldseta precedent

... It is the opinion of Delta that operations conducted underthe previous reliefgranted by exemption 6140 and the conditions and limitations ofthat exemption remain in place, there is no precedent being set with our request. Furthermore, the issuance of this exemption is not a controversial issue. This petition does not seek to establish a precedent, but merely continue an accepted and established practice. Accordingly, Delta requests that publication in the Federal Register be waived as unnecessary (14 CFR §11.87). 

### NoAdverse Effect on Public Safety The conditions and circumstances, in regard to public interest and equivalent levels of safety, which warranted the original grant ofexemption 6140, continue to exist. Exemption 6140 has been in use by Delta for over 20years with no known compromise of safety. 

### Conclusion Based on the information provided in this petition, granting Delta the same relief as permitted in Exemption No. 6140, will allow Delta to continue to provide the same level of service and safety without interruption.
