- Inspection intervals are scheduled at equal intervals throughout the total inspection cycle, regardless of when inspections were actually completed.
Inspection Types
- Pre-Flight Inspections:
- PR
- PLI or WAI
- Pre-Flight validity period ends when the selected time period has expired or when the specified flying period expires, whichever occurs first.
- End-of-Runway Inspection:
- EOR
- Performed immediately prior to take-off at a designated location.
- Thru-Flight Inspection:
- TH
- After each flight, when a turnaround sortie or a continuation flight is scheduled and a BPO inspection is not required.
- Quick Turn Inspection:
- QT
- An abbreviated thru-flight inspection authorized by MDS specific -6 TOs.
- Basic Post-Flight Inspection:
- BPO
- A more thorough check than the PR or TH inspections.

- PR/BPO
- Consolidates the requirements of the PR and BPO inspections into a single inspection.
- Hourly Post-Flight Inspection:
- HPO
- Accomplished at equally spaced intervals as specified in the applicable MDS specific -6 TO.
- Periodic Inspection:
- PE
- Due upon accrual of the number of flying hours, operating hours, or at the expiration of a calendar period specified in the applicable MDS specific -6 TO.
- Phase Inspections:
- PH
- Consolidation of the BPO, periodic inspection, and/or HPO requirements into work decks having approximately the same work content and approximately the same number of clock hours for accomplishment.
- Isochronal Inspection:
- ISO
- Translates flying hour utilization rates into calendar periods, usually expressed in days.
- Minor ISO Inspection:
- MIN
- Checks certain components, areas, or systems of the aerospace vehicle to determine if conditions exist that could result in failure or malfunction prior to the next scheduled inspection.

- Letter checks (A through D)
- Specify the inspection period in either flying hours or calendar days.
- No-Fly Calendar Inspections:
- 30-Day Inspection
- 90-Day Inspection
- Required when aerospace vehicles do not fly for a consecutive number of days.### 30-Day Calibration Inspection
- Aerospace vehicles that have completed a PH or ISO inspection within the 30-day period will use the PH/ISO post-dock date to start the 30-day no-fly clock.
90-Day Inspection
- When an aerospace vehicle does not fly for 90 consecutive days (excluding ground training and alert/immediate response aerospace vehicles), the following tasks must be accomplished before the vehicle is returned to operational status:
- Perform a BPO or equivalent inspection.
- Perform an operational check of all functional aerospace vehicle systems except landing gear retraction (unless specified in the MDS specific -6 or -2 TO).
- Accomplish all lubrication requirements.
- Perform any additional inspection or maintenance requirements determined by the GP/CC.
Transfer Inspections
- See Chapter 8 for procedures.
Acceptance Inspections
- Lead Command will determine if an acceptance inspection is required for all newly assigned or organic/contract depot repaired vehicles/engines and equipment prior to being placed in service.
- The scope of these inspections will consist of:
- Preparation for Use IAW end-item TO.
- Service Inspection (SI) IAW applicable workcard.
- Operational Check IAW end-item TO.
- An acceptance inspection will be accomplished within 30 days of equipment receipt, and an Acceptance Inspection Deficiency Report (AIDR) will be documented in the Joint Deficiency Reporting System (JDRS) IAW TO 00-35D-54.
One Time Inspections (OTIs)
- OTIs are used to verify the existence of suspected equipment conditions or malfunctions.
- TCTOs directing an OTI must indicate whether previous inspections satisfy the one-time requirement.

Inspection Cycle
- Lead commands may authorize aerospace vehicles to use a modified inspection workcard deck during contingencies and increased readiness conditions.
- The SM designates and publishes workcards in conjunction with the Lead Command for use during these periods.
- Inspection intervals are scheduled at equal intervals throughout the total inspection cycle, regardless of when inspections were actually completed.
Inspection Types
- Pre-Flight Inspections:
- PR
- PLI or WAI
- Pre-Flight validity period ends when the selected time period has expired or when the specified flying period expires, whichever occurs first.
- End-of-Runway Inspection:
- EOR
- Performed immediately prior to take-off at a designated location.
- Thru-Flight Inspection:
- TH
- After each flight, when a turnaround sortie or a continuation flight is scheduled and a BPO inspection is not required.
- Quick Turn Inspection:
- QT
- An abbreviated thru-flight inspection authorized by MDS specific -6 TOs.
- Basic Post-Flight Inspection:
- BPO
- A more thorough check than the PR or TH inspections.
- Combined Pre-Flight/Basic Post-Flight Inspection:
- PR/BPO
- Consolidates the requirements of the PR and BPO inspections into a single inspection.
- Hourly Post-Flight Inspection:
- HPO
- Accomplished at equally spaced intervals as specified in the applicable MDS specific -6 TO.
- Periodic Inspection:
- PE
- Due upon accrual of the number of flying hours, operating hours, or at the expiration of a calendar period specified in the applicable MDS specific -6 TO.
- Phase Inspections:
- PH
- Consolidation of the BPO, periodic inspection, and/or HPO requirements into work decks having approximately the same work content and approximately the same number of clock hours for accomplishment.
- Isochronal Inspection:
- ISO
- Translates flying hour utilization rates into calendar periods, usually expressed in days.
- Minor ISO Inspection:
- MIN
- Checks certain components, areas, or systems of the aerospace vehicle to determine if conditions exist that could result in failure or malfunction prior to the next scheduled inspection.
- Major ISO Inspection:
- MAJ
- A thorough inspection of the entire aerospace vehicle, individual requirements may be more extensive in scope than previous inspection items.
- Home Station Check Inspection:
- HSC
- Arranged and designed for accomplishment upon expiration of a specified short-term calendar interval.
- Programmed Depot Maintenance:
- PDM
- An inspection requiring skills, equipment, and/or facilities not normally possessed by operating locations.
- Aerospace Vehicle Manufacturer Inspections:
- Letter checks (A through D)
- Specify the inspection period in either flying hours or calendar days.
- No-Fly Calendar Inspections:
- 30-Day Inspection
- 90-Day Inspection
- Required when aerospace vehicles do not fly for a consecutive number of days.### 30-Day Calibration Inspection
- Aerospace vehicles that have completed a PH or ISO inspection within the 30-day period will use the PH/ISO post-dock date to start the 30-day no-fly clock.
90-Day Inspection
- When an aerospace vehicle does not fly for 90 consecutive days (excluding ground training and alert/immediate response aerospace vehicles), the following tasks must be accomplished before the vehicle is returned to operational status:
- Perform a BPO or equivalent inspection.
- Perform an operational check of all functional aerospace vehicle systems except landing gear retraction (unless specified in the MDS specific -6 or -2 TO).
- Accomplish all lubrication requirements.
- Perform any additional inspection or maintenance requirements determined by the GP/CC.
Transfer Inspections
- See Chapter 8 for procedures.
Acceptance Inspections
- Lead Command will determine if an acceptance inspection is required for all newly assigned or organic/contract depot repaired vehicles/engines and equipment prior to being placed in service.
- The scope of these inspections will consist of:
- Preparation for Use IAW end-item TO.
- Service Inspection (SI) IAW applicable workcard.
- Operational Check IAW end-item TO.
- An acceptance inspection will be accomplished within 30 days of equipment receipt, and an Acceptance Inspection Deficiency Report (AIDR) will be documented in the Joint Deficiency Reporting System (JDRS) IAW TO 00-35D-54.
One Time Inspections (OTIs)
- OTIs are used to verify the existence of suspected equipment conditions or malfunctions.
- TCTOs directing an OTI must indicate whether previous inspections satisfy the one-time requirement.
- OTIs are developed and issued under the same guidelines as any other ALC issued TCTO.
In Process Inspection (IPI)
- An IPI is an additional inspection or verification step at a critical point in the installation, assembly, or reassembly of a system, subsystem, or component.
- IPIs are either TO, MAJCOM, or locally directed and are accomplished by IPI certified personnel.
Aerospace Vehicles in Storage
- Storage time will be accrued in accordance with TO 1-1-17 and applicable MDS specific TOs.
- For aerospace vehicles in storage exceeding 15 calendar days, time in storage is not charged against the calendar time for the next scheduled home station check, minor, or major inspection.
Inspection Workcards
- Inspection workcards outline the minimum inspection requirements and provide each technician with a standardized inspection guide.
- Workcards are grouped by the recommended type of technician required to accomplish the inspection so that all requirements listed on any particular card can normally be accomplished by one individual.
Inspection Intervals
- Intervals for Air Force aerospace vehicle inspections are prescribed in applicable Mission Design Series (MDS) specific -6 TO maintenance manuals, item technical orders, inspection workcards, checklists, commercial manuals, or depot engineering data.
- Inspection concepts for aerospace vehicles include:
- Periodic
- Phase
- Isochronal
- Programmed Depot Maintenance (PDM)
