This may be accomplished by inserting a copy of this AD into the AFM.This requirement may be actioned and signed for by a pilot having at least a private pilots licence.Note 1: Fairchild Service Letter 226-SL-017, Fairchild Service Letter 227-SL-033, and Fairchild Service Letter CC7-SL-023, all FAA Approved and dated26 August 1998; Revised 2 September 1998, address the subject matter of this AD.2. For all aeroplanes - Do the following actions at the times specified in the initial inspection or overhaul column and the repetitive inspection or overhaul column in Table 2 of this AD:a. For aeroplanes equipped with a pitch trim actuator P/N DL5040M5,P/N DL5040M6, or P/N DL5040M8 - Measure the freeplay of the pitch trim actuator and inspect the pitch trim actuator for rod slippage using the INSTRUCTIONS section of Fairchild Aircraft SA226 Series Service Letter (SL) 226-SL-005 or Fairchild Aircraft SA227 Series SL 227-SL-011, both Revised: 3 August 1999; or Fairchild Aircraft SA227 Series Service Letter CC7-SL-028, Issued: 12 August 1999, as applicable.b. For aeroplanes equipped with a pitch trim actuator P/N 27-19008-001,P/N 27-19008-002, P/N 27-19008-004, or P/N 27-19008-005 - Do a functional inspection of the pitch trim actuator using the INSTRUCTIONS section of Fairchild Aircraft SA226 Series SL 226-SL-014, Fairchild Aircraft SA227 Series SL 227-SL-031, or Fairchild Aircraft SA227 Series SLCC7-SL-021; all Revised: 1 February 1999; as applicable.c. For aeroplanes equipped with a pitch trim actuator P/N 27-19008-006 orP/N 27-19008-007 - Overhaul the pitch trim actuator following the applicable maintenance manual.

5. For all aeroplane Models SA227-CC and SA227-DC - Do not install as a replacement any of the following pitch trim actuators or FAA- approved equivalent P/Ns:a. P/N 27-19008-001;b. P/N 27-19008-002;c. P/N 27-19008-004;d. P/N 27-19008-005;e. P/N DL5040M5; orf. P/N DL5040M6.Note 2: FAA AD 2007-16-03 Amdt 39-15142 dated 27 July 2007 refers. This AD supersedes FAA AD 98-19-15R and AD 2000-03-17.
Compliance:
1. Remains unchanged as detailed in AD/SWSA 226/85 Amdt 1 as - Before further flight after 14 September 1998; or in the case of aircraft with actuators P/N27-19008-004, or P/N 27-19008-005, before further flight after 23 February 2000.Installation of any FAA-approved pitch trim actuator other than P/N27-19008-001, P/N 27-19008-002, P/ N 27-19008-004, or P/N 27-19008-005 terminates the actions detailed in Requirement 1 of this AD.2. As detailed in Table 2 of this AD.3. Before further flight when any of the following occurs:a. The pitch trim actuator is inspected following Requirement 2 of this AD and the freeplay limitations are exceeded, rod slippage is found, or a ratcheting sound occurs, as specified in the applicable service letters; orb. The installed pitch trim actuator reaches its repetitive replacement time as specified in table 2 of this AD.4. From the effective date of this AD.5. From the effective date of this AD.
This Airworthiness Directive becomes effective on 25 October 2007.
Background:
This AD results from reports of mechanical failure of the pitch trim actuator causing the horizontal stabilizer to move to full aircraft nose up. The issuing of this AD is intended to detect excessive freeplay or rod slippage in the pitch trim actuator, which, if not detected and corrected, could result in pitch trim actuator failure. It is also intended to lessen the severity of pitch upset if a pitch trim actuator mechanical failure occurs. These conditions could lead to possible loss of control. The issuing of this AD will also eliminate the use of certain pitch trim actuators that require frequent critical inspections or replacements.This AD supersedes AD/SWSA226/68 Amdt 5 and AD/SWSA226/85 Amdt 1 which are cancelled.
