1. THIS SECTION CONTAINS INSPECTION REQUIREMENTS THAT WILL BE ACCOMPLISHED AFTER THE ACCRUAL OF A SPECIFIC NUMBER OF FLYING HOURS, EQUIPMENT HOURS OF OPERATION, A LAPSE OF CALENDAR TIME, OR

AFTER THE OCCURRENCE OF A SPECIFIC OR UNUSUAL CONDITION.

2. THE CALENDAR AND/OR SPECIAL HOURLY REQUIREMENTS, WHEN DUE, MAY BE ADDED TO, AND ACCOMPLISHED AT THE NEXT HOURLY POSTFLIGHT (ENGINE ONLY) OR AIRCRAFT PERIODIC INSPECTION, AS APPROPRIATE.

HOWEVER, A REQUIREMENT WHICH REPRESENTS A HEAVY WORKLOAD OR INVOLVES MULTIPLE INSTALLATIONS

MAY BE ACCOMPLISHED IN APPROPRIATE SEGMENTS AT CONSECUTIVE PERIODS.

3. THE CONDITIONAL REQUIREMENTS, WHEN DUE, MAY REQUIRE ACCOMPLISHMENT AS SOON AS POSSIBLE AFTER

THE OCCURRENCE OF THE CONDITION OR PRIOR TO FURTHER FLIGHT.

NOTE

• AN ASTERISK PRECEDING AN ITEM INDICATES THAT ITEM MAY BE OVERFLOWN BY NO MORE THAN 10 HOURS FOR ITEMS WITH INTERVALS OF 300 HOURS OR LESS. ASTERISK ITEMS WITH INTERVALS IN EXCESS OF 300 HOURS MAY BE OVERFLOWN BY NO MORE THAN 30 HOURS. IF AN ITEM IS OVERFLOWN, THE NEXT SCHEDULED INSPECTION TIME SHOULD BE ADJUSTED TO REFLECT THE TOTAL HOURS OVER-

FLOWN.

• ITEMS (OTHER THAN AS STATED IN ABOVE NOTE) BECOMING DUE DURING THE FLYING DAY MAY BE

ACCOMPLISHED AT THE END OF THE FLYING DAY.

NOTE

• IF CHANGES TO INITIAL OR RECURRING AIRCRAFT STRUCTURAL INTEGRITY INSPECTIONS (ASIP)

(REFERENCE WORK UNIT CODE 11---) RESULT IN AN AIRCRAFT WHICH HAS OVERFLOWN, OR

WILL OVERFLY THE NEW FLIGHT HOUR INSPECTION REQUIREMENT BEFORE THE NEXT SCHED-

ULED INSPECTION, THEN AUTHORIZATION IS GRANTED TO DO THE NEW INSPECTION NO LATER

THAN THE NEXT SCHEDULED INSPECTION INTERVAL NOT TO EXCEED THE NEXT SCHEDULED PE-

RIODIC INSPECTION (TO 1T-38C-6WC-3), WHICHEVER IS LESS. FOR EXAMPLE, OVERFLIGHT OF

THE 125 HOUR INSPECTION WOULD BE DONE AT THE NEXT SCHEDULED 125 INTERVAL, OVER-

FLIGHT OF THE 225 HOUR INSPECTION WOULD BE DONE AT THE NEXT SCHEDULED 225 INTER-

VAL, ETC. IN NO CASE WILL OVERFLIGHT OF THE NEW INSPECTION BE EXTENDED BEYOND THE NEXT SCHEDULED PERIODIC INSPECTION. AFTER INITIAL COMPLIANCE WITH THESE INSPECTIONS, ALL FUTURE INSPECTIONS WILL BE REQUIRED AT THE INTERVALS SPECIFIED.

• THE WING INSTALLED ON A FUSELAGE IS NOT NECESSARILY THE ORIGINAL WING. THEREFORE, THE FUSELAGE AND WING TIME MAY NOT BE THE SAME. ACCORDINGLY, FUSELAGE AND WING

TIMES MUST BE COMPUTED/TRACKED SEPARATELY. THE INSPECTION INTERVALS REFLECTED IN

THE FOLLOWING PARAGRAPHS REPRESENT FUSELAGE HOURS FOR FUSELAGE COMPONENTS

AND WING HOURS FOR WING COMPONENTS.

• FOR AIRCRAFT IN CATEGORY 1, THE INSPECTION TIME INDICATES THE TOTAL CUMULATIVE

HOURS FOR THE FUSELAGE/WING (AS APPROPRIATE) AS REFLECTED IN THE AIRCRAFT

RECORDS.

• FOR AIRCRAFT IN CATEGORIES 3 THROUGH 8, THE INITIAL INSPECTION TIME INDICATES THE FU-

SELAGE/WING (AS APPROPRIATE) CUMULATIVE HOURS SINCE ASSIGNMENT TO THE CATEGORY 3

THROUGH 8 ROLES. ANY PREVIOUS TIME IN CATEGORY 1 SHALL NOT BE CONSIDERED IN COM-

PUTING THE INITIAL INSPECTION TIME FOR CATEGORY 3 THROUGH 8 AIRCRAFT. THE INITIAL IN-

SPECTION OF THE DRAIN HOLES, FASTENER HOLES, AND ROOT RADIUS MUST BE DONE

BEFORE THE COMPONENT (UNLESS A NEW SPARE) CAN BE FLOWN IN THE 3 THROUGH 8 ENVI-

RONMENT.

• THE INSPECTION INTERVALS REFLECTED IN THIS MATRIX ARE THE MAXIMUM AND SHOULD NOT

BE EXCEEDED; HOWEVER, TO FACILITATE EASE OF MAINTENANCE, THEY MAY BE ADDED TO

AND DONE AT AN EARLIER SCHEDULED INSPECTION. ALSO, REFER TO SECTION I, INTRODUC-

TION FOR SPECIAL INSTRUCTIONS.

• ANY CATEGORY CONVERSION ON USAF AETC AIRCRAFT REQUIRES PRIOR APPROVAL FROM HQ

AETC/A4M AND THE T-38 SYSTEM PROGRAM OFFICE. A CATEGORY 5 (SUPT) AIRCRAFT CANNOT

FLY IN ANY CATEGORY 3 (IFF) SYLLABUS WITHOUT CONVERSION. ADD AN ENTRY INTO AIR-

CRAFT AFTO FORM 95 WHEN A CONVERSION IS MADE, INCLUDING DATE AND AIRFRAME HOURS

AT THE TIME OF CONVERSION.

• WHEN CONVERTING FROM CATEGORY 3 (IFF) TO CATEGORY 5 (SUPT) USAGE, CONTINUE ALL

CATEGORY 3 INSPECTIONS UNTIL THE CATEGORY 3 INTERVAL, EITHER INITIAL OR RECURRING, IS SATISFIED. THEREAFTER, USE THE CATEGORY 5 INSPECTION INTERVAL. CATEGORY 3 INSPEC-

TIONS CAN BE DONE EARLIER THAN SCHEDULED AT THE DISCRETION OF MAINTENANCE TO

SIMPLIFY THE TRANSITION TO CATEGORY 5 INSPECTIONS.

• WHEN CONVERTING FROM CATEGORY 5 (SUPT) TO CATEGORY 3 (IFF) USAGE, USE CATEGORY 3 (IFF) INSPECTION INTERVALS, INITIAL AND RECURRING, AFTER USAGE BEGINS. TREAT ACCUMU-

LATED CATEGORY 5 (SUPT) HOURS UP TO THE USAGE CHANGE AS CATEGORY 3 (IFF) HOURS

FOR PLANNING THE NEXT SCHEDULED CATEGORY 3 (IFF) INSPECTION. WHEN THIS RESULTS IN

AN OVERFLY CONDITION, REFER TO THE FIRST NOTE BULLET ABOVE FOR OVERFLY LIMITS.

IDENTIFIES ONE RIGHT-HAND AND ONE LEFT-HAND FASTENER.

• AIRCRAFT OVERDUE FOR INITIAL INSPECTION SHOULD BE INSPECTED NO LATER THAN THE

NEXT 450-HOUR PERIODIC INSPECTION.

• THOSE AIRCRAFT WHICH WERE INSPECTED BEFORE THE INITIAL INTERVALS LISTED BELOW MAY USE THE NEW INITIAL INTERVAL FOR THE SECOND INSPECTION. FOR EXAMPLE, IF A WING WAS

INSPECTED AT 1100 WING HOURS, THE NEXT AREA ONE INSPECTION WOULD BE DUE AT 1800
