When a JT15D Borescope Inspection Is Called For
Most JT15D borescope inspections fall into one of four situations. The first is routine compliance, where Pratt & Whitney maintenance criteria or your operating rules call for an internal look at a set interval. The second is a pre-purchase or pre-lease evaluation, where a buyer, seller, or lender needs an independent read on internal condition before money changes hands. The third is a post-event inspection following a foreign object ingestion, an overtemperature, a hot start, or any other occurrence that gives reason to look inside. The fourth is a change in trend data, where indications have shifted enough that a visual confirmation is the sensible next step before deciding on further work.
In each case the value is the same. A JT15D engine borescope answers the question of internal condition without the cost, downtime, and disturbance of pulling the engine apart.
What a JT15D Internal Inspection Covers
Using the engine dedicated inspection ports, our technicians examine the compressor, combustion, and turbine sections. Blades and vanes are checked for cracking, erosion, burning, and impact damage. The combustion liner is examined for distress, and the turbine section is assessed for the wear patterns that matter on this engine.
Findings are measured against published Pratt & Whitney limits rather than opinion, and they are captured as high-resolution images so you can see exactly what the inspector saw. That documentation is what makes a borescope defensible later, whether the audience is a regulator, an insurer, or a buyer.
Pre-Purchase and Pre-Lease Evaluations
A JT15D pre-purchase inspection is one of the most common reasons operators call us, and it is the one where independence matters most. Brokers, buyers, and lenders all want an assessment that is not coming from the party selling the aircraft. Our reports are written to be read by someone who was not in the room, which means the condition of the engine is stated plainly and supported by images.
The result is a document you can negotiate against. If the engine is sound, you have evidence of it. If it is not, you have a specific, photographed list of what was found and what addressing it would involve.
What You Receive
Every inspection produces a written report covering the methodology used, the components inspected, a condition assessment of each, high-resolution imagery of the findings, and a clear recommendation for next steps. Where something needs attention, we say what it is, how severe it is, and what the realistic options are.
What a JT15D Borescope Inspection Costs
Cost depends on scope, location, and how much documentation you need. A routine compliance borescope and a fully documented pre-purchase evaluation are different pieces of work and are priced separately. We provide clear pricing before anything is scheduled, so the number is settled before the engine is opened for inspection.
If the Findings Warrant Further Work
A borescope tells you what is happening inside the engine. It does not, by itself, fix anything. What separates a borescope at Hale Aircraft from one performed by a shop that only inspects is what can happen next, under the same roof and the same FAA Part 145 Repair Station certificate.
If the findings point to hot section distress, we perform the JT15D hot section inspection here. If a component needs repair, our JT15D engine repair work includes in-house non-destructive testing, machining, and welding, so parts are not waiting in transit on an outside vendor. If the engine is due for a full JT15D engine overhaul, we handle that as well.
And when the work is finished, we can verify it. Hale Aircraft operates the only JT15D test cell in the Southeast, which means the engine can be run and its performance confirmed before it goes back on the aircraft rather than after.
That continuity is the practical reason operators start with us. One inspection, one shop, one set of records, and no handoffs between vendors who have never seen the engine.
Frequently Asked Questions
How long does a JT15D borescope inspection take?
A standard JT15D borescope inspection typically completes in a few hours, depending on scope and engine accessibility. Pre-purchase inspections that include detailed documentation and additional checks take longer.
Can a JT15D borescope inspection be performed at my location?
Yes, in many cases. Hale Aircraft offers on-location borescope inspections for routine compliance and pre-purchase evaluations. Contact us to discuss logistics for your situation.
How much does a JT15D borescope inspection cost?
Cost varies based on scope, location, and documentation requirements. Hale Aircraft provides clear pricing before scheduling. Pre-purchase inspections that include extensive documentation are priced separately from routine compliance borescopes. events. Hale Aircraft performs both.
What is included in the borescope inspection report?
Reports include inspection methodology, components inspected, condition assessment, high-resolution images of significant findings, and clear recommendations. Reports are suitable for compliance records, aircraft transactions, and insurance documentation.
What happens if the borescope inspection finds issues?
Hale Aircraft provides a clear assessment of severity and recommended next steps. Because we handle repair, NDT, machining, welding, and test cell verification all in-house, findings move directly into repair workflow if you choose to proceed.
How is a borescope inspection different from a hot section inspection?
A borescope inspection is non-invasive and does not require disassembly. A hot section inspection is a structured maintenance event that includes disassembly, cleaning, NDT, repair, and reassembly of hot section components. Borescope is often the diagnostic that triggers a hot section inspection.
