Compliance – Mandatory: An Airworthiness Directive has been requested on the matter covered by this Service Bulletin.
Civil Airplanes: Textron Aviation considers this to be a mandatory inspection/modification and it should be accomplished no later than the next Annual/Phase 1 Inspection, as applicable, after receipt of this Service Bulletin and annually thereafter.
Military Airplanes: For compliance information on military airplanes affected by this Service Bulletin, contact the appropriate headquarters.
Reason: This Service Bulletin is being issued to provide safety information once more regarding usage of unauthorized or altered flight control (gust) locks on various Beech propeller airplanes. Numerous accidents and casualties over the years have resulted from the failure of a pilot to remove an unauthorized or altered flight control (gust) lock prior to attempted takeoff. A review of the records from these accidents, dating back to 1975, has revealed that many of the accidents involved use of a make-shift control (gust) lock that was not the one provided by Textron Aviation. In some cases, a common bolt or nail had been inserted through the hole provided in the control column for the flight control (gust) lock. Such a device does not meet the requirements for flight control (gust) locks as defined in 14 CFR 23.679, which states in part: “If there is a device to lock the control system on the ground or water, (a) There must be a means to (1) give unmistakable warning to the pilot when the lock is engaged…”
Warranty: None.
Labor: The following information is for planning purposes only:
NOTE: No warranty coverage will be allowed for the inspection portion of this Service Bulletin.
Estimated man-hours: 0.5 hours
Suggested number of technicians: 1
The above is an estimate based on experienced, properly equipped technicians complying with this Service Bulletin. Occasionally, after work has started, conditions may be found that could result in additional man-hours.

From King Air Communiqué 2016-11:
Issued: December 2016
ATA 27 – Universal Travel Board Instruction Manual
90 Series (except F-90); 200 Series; 300/B300 Series
Universal Travel Board instructions have been included in the respective Maintenance Manuals for each of the models listed above. If you are in possession of the Universal Travel Board Instructions Manual, Part Number 98-32928E, please disregard and use the appropriate Maintenance Manual instructions for the applicable model. However, this manual may still be used on other airplane models.
ATA 35 – Oxygen System Barometric Pressure Switch Relocation
FL-954, FL-1010, FL-1031 and after
The barometric pressure switch associated with the auto-deployment oxygen system has been relocated from the forward side of the right-hand emergency exit to below the emergency exit and just forward of the right hand forward cabin table.
The barometric pressure switch can be accessed by removing the upholstery panel that covers the right hand forward table. To remove the panel, grasp the panel on the lower portion of the panel and lift up and inboard. The switch is located just forward of the table.
King Air 350i airplanes equipped with the Slick Interior option will have the barometric pressure switch in the new location. However, the lower upholstery panel is one piece from front to back and requires removal of the whole panel. The Model B300C (FM serial numbers) will have the barometric pressure switch in the original location.
