### "I" CHECK PROCEDURES

Note: Complete an "I" CHECK DISCREPANCY REPORT form ea ch time this inspection is performed. Discrepancies found in secondary structure, such as stringers, etc., must be repaired. Contact Hawker Beechcraft Corporation Airline Technical Support if any cracks are found in the ve rtical and horizontal stabiliz er structure. Applicable repair procedures may be found in the Model 1900 Airliner Series Structural Repair Manual . Report each discrepancy found and the corrective action taken to clear the discrepancy. If no discrepancies were found, write the phrase "NO DISCREPA NCIES FOUND" on the discrepancy report form. Please mail the completed form to Hawker Beechcraft Corporation Airline Technical Support at the address indicated at the bottom of the form. If required, mark any discrepant areas on a photo a nd attach it to the discrepancy report form.

An example of this report form is provided in the "FORMS" section of this manual. Copy the form as required for this inspection.

The initial inspection described herein is to be performe d ten years from the date of manufacture of the airplane, then every 1,200 hours or two years, whichever occurs first. Airplanes that have surpassed the ten year threshold at the time of issuance of this Empennage in spection program must comple te the initial inspection no later than two years fr om April 25, 2003.



### GENERAL INSPECTI ON PROCEDURES

Note: For corrosion control and treatment, refer to Model 1900 Airliner Series Corrosion Control Manual, P/N 114-

590021-197

.

The following items must be accomplished prior to performing the required inspection:

1. Check the entire vertical a nd horizontal stabilizer fo r indications of working rivets, dam aged or worn areas, loose paint, s kin

cracks and corrosion.

Note: This inspection provides specific locations and structural examples of items to look for; a visual inspection of all surrounding structure in the general area must also be performed. 2. Wash and degrease the vert ical and horizontal stabilizer structure, if required ( Ref. Chapter 20-10-01, AIRPLANE CLEANING

AND WASHING in the Model 1900 Airliner Seri es Corrosion Control Manual, P/N 114-590021-197 ).



### INSPECTION ACCESS PROCEDURES

The following procedures provide information required to gain a ccess to a particular inspection area or prepare the airplane fo r inspection.

Note: When gaining access to the area to be inspected, make sure that the area is clean and free of foreign substances. Clean area as required.

1. If not previously accomplishe d, perform the requirements of Kit P/N 114-4060 to provide access to the inspection areas. Make appropriate logbook entries denoting the Kit number and the Kit serial number installed.

2. Remove all access panels fr om the left side of the vertical stabilizer and a ccess panel 331GR from the right side of the ver tical stabilizer (Ref. Chapter 6-50-00, HORIZONTAL AND VERTICAL STABILI ZER ACCESS PANELS in the Model 1900D Airliner Maintenance Manual, P/N 129-590000-15 ).

3. Remove all access panels except 351 CTL and 352CTR from the to p and bottom sides of the horizontal stabilizers (Ref. Chapter 6-50-00, HORIZONTAL AND VERTICAL STABILIZER AC CESS PANELS in the Model 19 00D Airliner Maintenance Manual, P/N 129-590000-15 ).

4. Remove access panels 332ATC, 332BTC and 333ATC from the top of the vertical stabilizer (Ref. Chapter 6-50-00,

HORIZONTAL AND VERTICAL ST ABILIZER ACCESS PANELS in the Model 1900D Airliner Maintenance Manual, P/N 129-

590000-15 ).

5. Perform the required procedures in acco rdance with this check procedure. Use the "I" CHECK Sign-off form provided in this section to record completion of the tasks. Use the "I" CH ECK illustrations to aid you in the location of items being worked on or discussed when performing the procedure and inspection.



### INSPECTION RECO VERY PROCEDURE

The followin g procedures provide information required to restore the airplane to its normal condition after the inspection. Current as of May 1/13 Model 1900D Airliner Structural Inspection Manual “I“ CHECK- 001 7/16/2013 3:18:37 PM
