"I" CHECK PROCEDURES 

Note: Complete an "I" CHECK DISCREPANCY REPORT form each 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 vertical and horizontal stabilizer 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 DISCREPANCIES 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 and attach it to the discrepancy report form. 

An example of this report form is provided at the end of this section and in the "FORMS" section of this manual. 

Copy the form as required for this inspection. 

The initial inspection described herein is to be performed 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 inspection program must complete the initial inspection no 

later than two years from April 25, 2003. 

GENERAL INSPECTION PROCEDURES 

Note: For corrosion control and treatment, refer to Chapter 20-00-01 in the 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 and horizontal stabilizer for indications of working rivets, damaged or worn areas, loose paint, skin 

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 vertical and horizontal stabilizer structure, if required (Ref. Chapter 20-10-01, AIRPLANE CLEANING 

AND WASHING, Model 1900 Airliner Series Corrosion Control Manual). 

INSPECTION ACCESS PROCEDURES 

The following procedures provide information required to gain access to a particular inspection area or prepare the airplane for 

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 accomplished, perform the requirements of Kit No. 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 except panel number 26 from the top and bottom sides of the horizontal stabilizers. Remove access 

panels 33, 17 and 18 from the top of the vertical stabilizer (Ref. Figure 1). 

3. Remove all access panels from the left side of the vertical stabilizer and access panel 35R from the right side of the vertical 

stabilizer (Ref. Chapter 6-50-00, Model 1900/1900C Airliner Maintenance Manual). 

4. Perform the required procedures in accordance with this check procedure. Use the "I" Check Sign-off form provided in this 

section to record completion of the tasks. Use the "I" Check illustrations to aid you in the location of items being worked on or 

discussed when performing the procedure and inspection. 

INSPECTION RECOVERY PROCEDURES 

The following procedures provide information required to restore the airplane to its normal condition after the inspection. 

1. Install all access covers and panels.
