Airworthiness Directive · Amendment 39-14262 · Raytheon Aircraft Company Models 1900, 1900C, 1900C (C-12J), and 1900D Airplanes
Raytheon Aircraft Company Models 1900, 1900C, 1900C (C-12J), and 1900D Airplanes
This AD affects the following airplane models and serial numbers that are certificated in any category:
| Models | Serial Nos. |
|---|---|
| (1) 1900 | UA-3; |
| (2) 1900C | UB-1 through UB-74 and UC-1 through UC-174; |
| (3) 1900C (C-12J) | UD-1 through UD-6; and |
| (4) 1900D | UE-1 through UE-439. |
The FAA is adopting a new airworthiness directive (AD) for certain Raytheon Aircraft Company Models 1900, 1900C, 1900C (C-12J), and 1900D airplanes. This AD requires you to inspect all elevator hinge support attachments on both left and right elevators for loose and missing rivets, replace rivets if loose or missing rivets are found, inspect the elevator hinge joints for looseness and clearance of each elevator to its stabilizer, correct looseness and clearance if incorrect, and report results of the required inspections. This AD results from a report of excessive movement of the elevator and elevator trim. The hinge support attachment that attaches the elevator to the horizontal stabilizer was loose and had loose and missing rivets. The elevator counterweight horn showed evidence of rubbing against the horizontal stabilizer, indicating possible incorrect clearance. We are issuing this AD to detect and correct any looseness in the elevator hinge support attachments, which could result in binding of the elevator control system. This elevator binding could lead to loss of control of the airplane.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Inspect all elevator hinge support attachments on both left and right elevators on both left and right elevators for loose or missing rivets | Within 50 hours time-in-service (TIS) after the effective date of this AD | As specified in Raytheon Aircraft Company Safety Communiqué No. 261, dated August 2005, following the applicable Raytheon Aircraft Company Maintenance Manual, Chapter 5-20-07 and Structural Repair Manual, Chapter 51-40-02. |
| (2) If loose or missing rivets are found in the inspection required in paragraph (e)(1) of this AD, replace reviets | Before further flight | As specified in Raytheon Aircraft Company Safety Communiqué No. 261, dated August 2005, following the applicable Raytheon Aircraft Company Maintenance Manual, Chapter 5-20-07 and Structural Repair Manual, Chapter 51-40-02. |
| (3) Inspect the elevator hinge joints for looseness and the clearance of each elevator to its stabilizer | Within 50 hours TIS after the effective date of this AD | As specified in Raytheon Aircraft Company Safety Communiqué No. 261, dated August 2005, following the applicable Raytheon Aircraft Company Maintenance Manual, Chapter 5-20-07. |
| (4) If looseness of the elevator hinge joints or incorrect clearance between the elevators and their stabilizers is found, correct the discrepancies | Before further flight | As specified in Raytheon Aircraft Company Safety Communiqué No. 261, dated August 2005, following the applicable Raytheon Aircraft Company Maintenance Manual, Chapter 5-20-07. |
| (5) Report the results found in the inspections required in paragraph (e)(1) and (e)(3) of this AD. The Office of Management and Budget (OMB) approved the information collection requirements contained in this regulation under the provisions of the Paperwork Reduction Act of 1980 (44 U.S.C. 3501 and those following sections) and assigned OMB Control Number 2120-0056 | Within 7 days after the inspections required in paragraph (e)(1) and (e)(3) of this AD | In addition to Raytheon Aircraft Company, send a completed copy of the Raytheon Aircraft Company Elevator Inspection form, found in Raytheon Aircraft Company Safety Communiqué No. 261, dated August 2005, to Steven E. Potter, FAA, 1801 Airport Road, Wichita, Kansas 67209. Also include in your report TIS since elevator replacement, if elevator has been replaced. |
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
