Overview

This document is an Airworthiness Directive (AD) schedule for the Beechcraft D17S and G17S series aircraft, commonly known as the Staggerwing. Issued by the Civil Aviation Authority of New Zealand on August 31, 2000, it outlines specific inspection requirements to ensure the safety and airworthiness of these aircraft models. The directive is particularly focused on the control wheel shaft and its potential failure due to improper counterbore depth. Although there are currently no registered aircraft of this type in New Zealand, the schedule will be reactivated upon registration of any Beechcraft Staggerwing aircraft. The document emphasizes the importance of compliance with the outlined requirements to maintain safety standards.

  • The document is an Airworthiness Directive for Beechcraft D17S and G17S aircraft.
  • Inspection of the control wheel shaft is required to prevent failure.
  • A 3/8-inch hole must be drilled in the control wheel hub for inspection purposes.
  • Counterbore depth must not exceed 1 7/16 inches; otherwise, the shaft must be replaced.
  • This AD is applicable before the issuance of a New Zealand Airworthiness Certificate.

Control Wheel Shaft - Inspection

This section details the inspection requirements for the control wheel shaft of the Beechcraft D17S equipped with Beech Half-circle type control wheels. The directive specifies a series of steps to measure the counterbore depth in the control shaft. If the counterbore depth exceeds 1 7/16 inches, the shaft must be replaced. The inspection must be completed before the issuance of a New Zealand Airworthiness Certificate.

Applicability

The AD applies specifically to Beechcraft D17S aircraft with Half-circle type control wheels. It does not apply to those equipped with Bow-tie type control wheels.

Compliance

Compliance with the inspection requirements is mandated before the issuance of a New Zealand Airworthiness Certificate, ensuring that all safety measures are met prior to operation.

Safety notes

  • Failure to comply with the inspection requirements may lead to control column wheel shaft failure.

Issued 31 August 2000 Page 1 of 2 CAA of NZ Airworthiness Directive Schedule Beechcraft D17S and G17S Series (Staggerwing) 31 August 2000 Notes 1. This AD schedule is applicable to Beechcraft D17S (Staggerwing) aircraft, manufactured under Federal Aviation Administration (FAA) Type Certificate (TC) No. A-649, and Beechcraft G17S (Staggerwing) aircraft, manufactured under FAA TC No. A-779. 2. As there are no aircraft of this type currently registered in New Zealand this AD schedule is not being maintained. The schedule will be reactivated once the New Zealand Civil Aviation Authority receives an application to register an aircraft of this type. At that time the applicable ADs will include all those published by the state of design (FAA). 3. The date above indicates the amendment date of this schedule. 4. New or amended ADs are shown with an asterisk * Contents DCA/B17/1 Control Wheel Shaft - Inspection....................................................................................... 2 * DCA/B17/2 Cancelled .......................................................................................................................... 2 Error! No text of specified style in document. Beechcraft D17S and G17S Series (Staggerwing) Issued 31 August 2000 Page 2 of 2 CAA of NZ DCA/B17/1 Control Wheel Shaft - Inspection Applicability: Model D17S equipped with Beech Half-circle type control wheels. This AD is not applicable to Bow-tie type control wheels attached to the control shaft by three bolts through a flange on the shaft. Requirement: To preclude the possibility of failure of the control column wheel shaft due to too great a counterbore depth in the shaft, accomplish the following:- (1) Drill a 3/8-inch hole in the centre of the hub of the control wheels. Do not allow the drill to go more than 1 inch into the hub or the pin securing the wheel will be damaged. (2) Place a narrow scale or straight wire through the 3/8-inch hole and obtain the distance from the bottom of the counterbore (not the peak of the counterbore cone) to the face of the hub. (3) Insert a small hook scale or bent wire in the hole and obtain the distance from the end of the shaft to the face of the hub. (4) Subtract the distance obtained in step No. 3 from the distance obtained in step No. 2 to obtain the depth of the counterbore in the end of the shaft. If this distance is over 1 7/16 inches, the shaft must be replaced. All shafts having a counterbore less than 1 7/16 inches deep are satisfactory. (FAA AD 48-51-01 and Beech SB C-18-9 refer) Compliance: Before issue of New Zealand Airworthiness Certificate. Effective Date: 7 May 1999 * DCA/B17/2 Cancelled
