To detect cracking in the wing to fuselage attachment fittings at butt line 9 of Grum man Model G -159 airplanes, accomplish the following: a. W ithin 6 months time in service after the effective date of this AD, unless already accomplished, inspect the wing to fuselage attachment fittings, P /N s 159WM10064 and 159WM10065 (P /N 159WM10223 assembly), and P /N 159WM10045 at butt line 9 left and right, wing front beam for cracks, deforma tion, gaps, or improper shimming in accord ance with Grumman Gulfstream I Aircraft Service Change No. 190, dated June 28, 1971, or later FAA approved revision or in a m an ner approved by the Chief, Engineering and Manufacturing Branch, FAA Southern Region. b. If cracks, deformation, gaps, or im proper shimming are found when conducting the inspection required by paragraph a., within 100 hours time in service after detec tion correct in accordance with Aircraft Service Change 190 or in a manner approved by the Chief, Engineering and Manufacturing Branch, FAA Southern Region. c. Upon request of the operator, an FAA maintenance inspector, subject to prior ap proval of the Chief, Engineering and M anu facturing Branch, FAA Southern Region, may adjust the inspection time to coincide with inspections for wing corrosion required by AD 6 7-4-1. This amendment becomes effective November 26,1971.

I—.—2 FEDERAL REGISTER, VOL. 36, NO. 214— FRIDAY, NOVEMBER 5, 1971 21280 RULES AND REGULATIONS [Docket No. 11003; Arndt. 65-19] PART 65— CERTIFICATION: AIRMEN OTHER THAN FLIGHT CREWMEMBERS Military Air Traffic Control Tower Op erators; Experience Requirements for Facility Rating The purpose of this amendment to Part 65 of the Federal Aviation Regula tions is to allow military air traffic con trol tower operators to meet the practical experience requirements for a facility rating at a particular tower by having at least 6 months of experience as an air traffic control tower operator. However, that experience need not be had Cl) at that tower without a facility rating or (2) at a different tower with a facility rating there, as required of other Control tower operators. Interested persons have been afforded an opportunity to participate in the mak ing of this amendment by a notice of pro posed rule making (notice 71-11) issued on April 23, 1971, and published in the F ederal R eg ister on April 29, 1971 (36 F.R. 8051). Due consideration has been given to all comments presented in response to the notice. Four of the seven public comments received in response to the notice con curred in the proposal. The other three opposed the proposal. One of these as serted that the proposal would result in a derogation of safety. Another asserted that (1) if an Air Force controller were transferred frequently during the 6- month period, he might not acquire ade quate practical experience; (2) under the proposed rule civilian and military con trollers at joint-use facilities might not have the same qualifications; and (3) the proposed rule would lower standards without consideration of established air traffic control procedures and the need for maintaining the highest degree of safety in aviation. The third opposing commentator asserted that the facility ratings placed on certificates would be degraded. The FAA does not agree that any of these asserted results will be caused by this rule. The rule does not entitle an Air Force controller to a facility rating so that he may immediately control air traffic. It only relieves him of waiting 6 months at a particular tower, if he has satisfactorily served elsewhere as an air traffic control tojver operator for at least 6 months. He is still required to pass the skill requirements under § 65.37 that are applicable to each operating position in the tower at which the rating is sought. Safety would not be derogated because the rating will not be issued until the individual passes the practical test and demonstrates his competence as an air traffic control tower operator at the particular airport. It has therefore been determined to issue the amendment for the reasons stated in the notice. In its response to the notice, the Di rectorate of Operations, U.S. Air Force, recommended changing “ air traffic con trol tower operator” to “ air traffic con troller” so that the time served by controllers providing only radar ap proach control service could be applied to the 6 months experience requirement. However, this change is not necessary as to radar approach control service per formed as an airport traffic control func tion of a particular tower. While per forming this service a Rerson is serving as an air traffic control tower operator, and the time involved is applied to the 6 months experience requirement. In consideration of the foregoing, § 65.39 of the Federal Aviation Regula tions is amended, effective December 6, 1971, by adding the following flush para graph at the end thereof: § 6 5 .3 9 Practical experience require ments : facility rating. * * * * * However, an applicant who is a member of an Armed Force of the United States meets the requirements of this section if he has satisfactorily served as an air traffic control tower operator for at least 6 months.
