Bristow Alaska Inc. A part 135 helicopter operator based in Fairbanks Alaska would like to ask for an exemption to the federal aviation regulations part 43,3(g) and 43.3(h)(l). This exemption is similar to an already existing exemption (8697). ·-.-.,. 1 .•. 

### FAR 11.81 Requirements
(a) Your name and mailing address and, ifyouwish, other contact information such as a fax number, telephone number, or e-mail address; JeffJ. Ryhti Director ofMaintenance Bristow Alaska Inc. 1915 Donald Ave. Fairbanks, Ak 997012 907 452-1197 voice 907 452-4539 fax 907 378-7777 cell jeffery.ryhti@bristowgroup.com
(b) 

### The specific section or sections of14 CFR from which you seek an exemption; FAR43.3(g) and 43.3(h)(l)


### (c) The extent ofreliefyou seek, andthe reasonyotf.:seekthe relief; Bristow Alaska's would like to be exempt from all ofFAR 43.3(g) and 43.3(h)(l) Our request is to allow a pilot to remove and install batteries to prevent the battery from freezing in cold temperatures. We would also like to request that a pilot be allowed to remove and install pilot and passenger doors to facilitate external load operations.


### d) The reasons why grantingyour request would be in the public interest; that is, how it would benefitthe public as a whole; It is not practical to have a mechanic fly with the aircraft to a location to perform the maintenance function ofremoving and installing the doors for the helicopter to perform the external load operation or removing and installing the battery to prevent the freezing ofthe battery. This adds unnecessary cost to the customers and Jowers the performance ofthe aircraft which in some cases prevents thejobfrom being completed.


### (e) Thereasons why granting the exemption would not adversely affect safety, orhow the exemption would provide a level ofsafety at least equal to thatprovided by the rule from which you seekthe exemption; As a Part 135 helicopter operator working in a remott''area the maintenance actions ofremoving and replacing a battery can already beperformed by a pilot'underFARpart43.3(h) provided it is a result of mechanical difficulty. Bristowbelieves the opportunity to make a mistake would behigher when attempting to fix an aircraft with a discrepancy rathe11than preventing the discrepancy to begin with.

Bristow Alaska also believes it is safer in certain applications to remove a door for increased visibility while performing external load operations. Both ofthese maintenance functions can beperformed by elementary means and are not complicated in nature. Bristow Alaska will have a FAA approved training program addressing task accomplishment and required documentation for all the maintenance items pilots

are approved to perform.
(t) 

### A summary we can publish inthe FederalRegister, stating: (1) The rule from which you seekthe exemption; and (2) A briefdescription ofthe natureofthe exemption you seek; Bristow Alaska Inc. would like the exemption for FAR 43.3(g) and 43.3(h)(l) Ourrequest is to allow a pilot to remove and install batteries to prevent the battery from freezing in cold temperatures. We would also like to request that a pilot in a remote area be allowed to remove and install pilot and passenger doors as manyjobs require the aircraft to fly to a location remove the door for external load operations and then install the door and return back to its homebase. The maintenance functions mentioned above can beperformed by elementary means and are not complicated in nature and

are allowed to be performed by a pilot ifdue to a mechanical malfunction.


### (g) Any additional information, views or arguments available to supportyour request; and (h) If

### you wantto exercise the privileges ofyour exemption outside the United States, thereason why you need to do so. In the remote artie conditions we operate in it is notpractical to have maintenance personnel on board with the aircraft at all times. Likewise it would not be safe to leave maintenance at a remote location while the aircraft is performing its mission. This exemption would be on Bell 206 series, Bell 407 and EurocopterB0105 helicopters only operated under Part 135 AAIP maintenance program.
