Maintenance handovers: keep the records usable

When a technician leaves a team, their replacement needs to find out what was done to the aircraft, the result and what remains unresolved. If only the previous person knows the answers, the handover can turn into a search for information. Before they leave, ask the recipient to open the records and work through missing documents together.

Maintenance records contain evidence of work and aircraft follow-up. They do not replace a technician’s skills; they provide the information those skills depend on. A CAMO, or continuing airworthiness management organisation, manages the ongoing work needed to keep an aircraft airworthy.

Why the team’s time matters

Boeing’s 2026 Pilot and Technician Outlook forecasts demand for 728,000 new technicians between 2026 and 2045. Its scope is worldwide commercial aircraft with more than 30 seats, excluding business jets and civil helicopters. This is cumulative demand over twenty years, not 728,000 vacancies today.

ATEC and Oliver Wyman’s 2025 Pipeline Report estimates a certified mechanic shortage of 10% in 2025, falling to 7% in 2035, in US commercial air transport. These projections do not directly measure staffing available to a European business aircraft fleet.

In Europe, section 3.2.5 of EASA’s EPAS 2026 addendum makes competent personnel availability a priority and refers to action SPT.0107. This safety plan does not prescribe a new handover form.

These sources provide context. They do not establish that every maintenance shop is outsourcing more work or that software solves the shortage. If your team experiences departures, replacements or transfers between shops, understandable records can help the next person avoid searching for information already known.

What the recipient should be able to check

For a particular maintenance task, connect the aircraft or component identity to the documents that establish:

• the work performed and the maintenance instruction used, including its revision;
• the result, any measurements and replaced parts;
• the author, date and applicable approval;
• outstanding items, who owns each one and the next action.

A maintenance reference here means the technical instruction used for the work. A certificate of release to service, or CRS, records the release relating to the maintenance concerned. Filing the documents does not give someone the authority to replace the certifying staff’s signature.

Sending a link is insufficient: the recipient must be able to open the files using their own access and connect them to the correct aircraft. A scan can help, but it cannot recreate a missing attachment or establish a signature’s authenticity by itself.

A fictional example, from sending to verified receipt

This entire example is fictional. The people, aircraft DEMO-A01, serial number DEMO001 and document references relate to no real operation. The technical references must not be used for maintenance.

On 7 September 2026, Léa hands aircraft records coordination to Malik within the same team. The owner, operator and CAMO remain the same. Their REL-01 handover sheet organises the work; it is not a regulatory form.

1. Identify the documents being sent

Léa sends INDEX-01, version 1, with:

• IDENT-01: aircraft identity and serial number;
• TC-17: the work card for a cabin lighting check, signed by Nora on 6 September;
• REF-17: fictional reference DEMO-D17, revision C, cited on that card;
• CRS-17: the associated fictional certificate of release to service;
• SUIVI-01: the tracking statement, showing no outstanding technical work.

Card TC-17 refers to attachment A containing the check result. That attachment is missing from the package.

2. Keep the gap visible

At 09:15, Malik opens the files with his own account, checks the aircraft identity and spots the missing attachment. He records item A-01 as open, names Nora as the contact and requests an archive copy by 14:00. If no response arrives, he must escalate the item to the person designated in their procedures.

An oral explanation does not close the item. Its absence from the package also does not, by itself, establish that the check never happened or that the aircraft must be grounded. If the gap prevents a necessary technical status from being established, competent personnel must resolve that issue before a decision dependent on it.

3. Add evidence without rewriting history

At 13:40, Nora sends archive copy ANN-17-A and her response REP-01. At 14:20, Malik checks that the attachment matches the aircraft, card, date and stated check. He records his verification in VERIF-01.

In this example, only the export was incomplete: the attachment existed in the source records. There is no reason to rewrite the card or manufacture a new signature. At 15:00, Léa issues index version 2, recording the addition, its author and reason while retaining version 1.

4. Close the handover against a specific record set

At 16:00, Malik opens all of version 2 and signs receipt REC-01. It identifies the index received and the closure of A-01, linking to ANN-17-A, REP-01 and VERIF-01. Léa retains the receipt. If any item remained open, the receipt would need to identify it, its owner and the next deadline.

Malik confirms what he received and checked. He does not certify the aircraft’s entire airworthiness or issue a new CRS.

The rule and the proposed working method

Part-M point M.A.307 covers records transfers when an aircraft is permanently transferred between owners or operators, and when an owner contracts management to a CAMO or a CAO, a combined airworthiness organisation. The retention periods continue to apply to the recipient. Léa and Malik’s internal handover does not, by itself, constitute one of those transfers. See EASA’s rules, M.A.307.

M.A.305(g) requires clear, accurate entries and corrections that leave the original entry visible. This concerns the continuing airworthiness records system; it does not turn our fictional index into a prescribed regulatory document. See M.A.305 in EASA’s rules.

For your next handover, a short sheet can cover seven items: the aircraft, sender and recipient, index and version, checks performed, open items, owners and deadlines, and dated receipt. Adapt it to your organisation’s procedures. The useful result is straightforward: the next person can locate the evidence and knows which questions remain unanswered.
