New-hire training pipeline: why your March recruit won't save your July checks
I teach the type courses your new hires sit in, so let me say the quiet part: the day HR sends the offer letter is not the day your manpower problem starts shrinking. Between "welcome aboard" and "authorised to certify on type" there is a 9–12 month pipeline — and if your man-hour plan counts a recruit at full strength from month one, the plan is lying to you by exactly the amount that will hurt in the peak season.
01The pipeline clock, honestly
Here is a realistic timeline for a licensed B1 joining your organisation without the AW139/AW189 rating — the common case, because fully type-rated engineers with current authorisation rarely sit on the market:
| Phase | Months | Effective output |
|---|---|---|
| Notice period & onboarding | 1–2 | 0% |
| Type course (theory + practical), waiting for a course slot | 2–4 | 0% |
| Supervised consolidation on the line/hangar | 4–7 | ~40% |
| Solo mechanical work, not yet certifying | 7–10 | ~70% |
| Company authorisation assessment & issue | 10–12 | 90–100% |
Two details hide in that table. First, type course slots are the real bottleneck — AW189 and H160 courses are booked out months ahead, and missing a slot slides the whole pipeline by a quarter. Second, the supervised phase is not free: a trainee at 40% output consumes roughly 15–20% of a mentor certifying engineer's time. Two trainees in a hangar during the summer peak can be a net negative on certifying capacity for the first months.
02The worked example: hiring for the July peak
Your base runs AW139s, and next July–August you face two 600 FH checks plus the usual line load. The gap analysis says you're short 720 man-hours across 9 weeks — about 80 hours a week, or 2.2 fully-productive engineers. Management approves two hires "in good time." Define good time:
| Hire start date | Productivity in July | July–Aug hours given | Certifying hours |
|---|---|---|---|
| Previous October (9 months ahead) | ~90% | ~290 | Yes — authorised |
| January (6 months ahead) | ~40–50% | ~150 | No |
| March (4 months ahead) | ~30% | ~100 | No |
| May (2 months ahead) | ~0% | ~0 | Net negative (mentor drag) |
The March hire — which feels early — contributes barely a third of an engineer and, critically, zero certifying hours during the peak. If your gap is in certification (and during check season it usually is), no hire inside the same calendar half-year fixes it. The formula your plan should use:
typical: peak start − 9 to 12 months, per license category
03Why this keeps going wrong
- Headcount is reported, capacity is not. The organisation chart says +2 engineers in March; nobody's spreadsheet says "at 30% and non-certifying until autumn."
- Attrition resets the clock. Losing one authorised B1 in April doesn't cost you one headcount — it costs you the 10-month pipeline to rebuild that authorisation, plus the mentor hours of whoever supervises the replacement.
- Category mismatch. A B2 hire does nothing for a B1 shortfall. Pipeline timing must be planned per license category, not per total headcount.
- Training is scheduled around work — until work wins. In peak months the trainee's consolidation flying and the mentor's supervision are the first things squeezed, stretching the pipeline exactly when you need it shortest.
04What belongs in the man-hour plan
Under AMC1 145.A.30(d) your man-hour plan must reflect realistic availability — and "realistic" includes the pipeline. Three practices that survive audits and July: model every non-authorised engineer at their ramp percentage by month, not at 1.0 FTE; carry a certifying-hours line per category that only counts staff who will actually hold authorisation in the window; and run the hiring trigger backwards — when the plan shows a certifying shortfall in month N, the recruitment decision had to happen in month N−9. If that date is already in the past, the plan should show the shortfall honestly and price the contractor cover instead of pretending the recruit will be ready.
