This is Wingtip Blade Services' blade inspection report WBS-2026-031 for Quellmoor Ridge Wind Farm in May 2026. It covers a drone visual and ground-photography inspection of 36 blades, with detailed category 3 and category 4 findings and related repair, replacement, monitoring, and follow-up recommendations.
Key facts
- The report covers Quellmoor Ridge Wind Farm, which is recorded as having 12 Litware LT-32 turbines and 36 blades of 57.5 m.1
- The inspection dates were 2026-05-18 to 2026-05-22.1
- The inspection method was drone visual inspection with three passes per blade and ground photography.1
- The report date was 2026-06-03 and the lead inspector was Leilani Hartfield.1
- Across the inspection, 36 blades were inspected; there was one category 4 finding, four category 3 findings, and eleven blades with category 2 damage.1
- Category 3 means significant damage and requires repair within 6 months.1
- Category 4 means serious damage and requires repair or replacement within 3 months plus monthly drone checks.1
- Category 5 means critical damage and requires stopping the turbine.1
- WTG-04 had the highest overall blade category in the turbine summary: blade A category 2, blade B category 4, blade C category 2, and highest category 4.1
- Finding F-01 is a category 4 trailing-edge crack on WTG-04 blade B.2
- For F-01, blade serial LB575-19-1187 had a 0.9 m trailing-edge crack along the bond line between radius 37.6 m and 38.5 m, close to the spar cap.2
- For F-01, repair is not recommended at that location and WTG-04 blade B is to be replaced before 2026-09-30.2
- Until WTG-04 blade B is replaced, the crack is to be checked by drone every month and the turbine is to be stopped immediately if the crack exceeds 1.2 m.2
- Finding F-02 is category 3 leading-edge erosion on WTG-04 blade B, with coating loss between radius 52 m and 57 m and no exposed laminate.2
- Finding F-03 is category 3 lightning receptor damage on WTG-08 blade A; the tip receptor is burnt, the receptor is to be replaced within 6 months, and continuity of the down conductor is to be checked.2
- Finding F-04 is category 3 leading-edge erosion on WTG-09 blade C, with erosion between radius 50 m and 57 m, exposed laminate over 0.3 m, and a required leading-edge repair within 6 months.2
- Finding F-05 is a category 3 root gelcoat crack on WTG-11 blade C, located at radius 3.2 m, with repair within 6 months and a check at the next inspection.2
- The recommendations are to replace WTG-04 blade B before 2026-09-30 using a crane lift, repair category 3 findings within 6 months using rope access, and perform the next full inspection in May 2027.2

Summary and category scale
The inspection covered 36 blades.3 The summary reports one category 4 finding on WTG-04 blade B, four category 3 findings, and eleven blades with category 2 damage; all other blades were category 0 or 1.3
The report defines category 0 as no damage with no required action and category 1 as cosmetic with no required action.3 Category 2 is minor damage to be monitored at the next inspection.3 Category 3 is significant damage requiring repair within 6 months.3 Category 4 is serious damage requiring repair or replacement within 3 months and a monthly drone check.3 Category 5 is critical damage requiring the turbine to be stopped.3
The turbine-level summary records WTG-04 as the only turbine with highest category 4.3 WTG-08, WTG-09, and WTG-11 each have highest category 3.3
