### It explains the basis for our decision and describ es its effect. 

### T b c Bas i s for Our Dec i s ion B y letter dated F eb ru ary 17 , 2017, Mr. Kreg Doerr, on beha l f of R ow 44/ G lobal Eagle Entertainment (Ro w 44), petitioned the FAA to request a third extension to the time limit specified in exemption n o . 11071

. That exem ption provides time -lim ited reli ef from the requirements ofTitl e 1 4 , Code ofFederal Regulations ( 14 CFR) 25.571(e)(1) re lating to bird-strike damage tolerance. Exemption no. 11071 a ll ows the installation of sate lli te antenna radome s, which have not been shown to meet FAA bird

- strike-damage tolerance requ i rements, on Boeing Model 777-200 series airplan es . Exe mption no. 11071 B extended the expiration date of exempt ion no . 11071 from September 22, 2016, to March 22, 2017. Your rece nt pet ition req uests an additional 6-month extension to allow Row 44 time to complete the development of a full-compliance methodology , as indicated in exemption no. 11071. In your petition, you note that your project 's supplemental type certificate (STC) was issued on December 18, 2014 , a nd the updated analy s i s and testing requ ir ed to s how compliance to § 25.57 1 (e)(1) has not been completed. Your petition states that Row 44 is cu rrently in the final s ta ges of Boeing Model 777-200 a irplan e radome te s ting and analysis. The petition further states that , due to interpretation of the results generated, Ro w 44 believes that an additional data point/data set i s required to complete the analysis package t o ensurecompliance. and that an extension will allow Row 44 to complete the required testing and documentation to s upp o rt certif ic ation of the design to§ 25 .5 71 (c)( I).
