UH-72A Lakota: Controlling Erosion and Corrosion Is Your Responsibility


The Lakota may be a contractor logistics supported rotary wing aircraft, but maintainers are responsible for all inspections and services, including proper corrosion prevention control or CPC.

The areas of focus for corrosion prevention are listed in Chap 9 of the Maintenance Compliance Inspection (MCI) checklist, Corrosion Prevention Control Policy. They include:
  • unit SOP
  • Aircraft Notebook (ACN)
  • historical record documentation
  • maintainer training certification
Lakota units need to follow Army guidance and use the original equipment manufacturer (OEM) guidelines to control and prevent corrosion problems.

The OEM guidelines are found in MBB-BK-117, Corrosion and Erosion Control Guide (CECG), and the Standard Practices Manual-Corrosion Inhibiting and Removal Procedures.

The CECG provides checks and procedures that will improve aircraft corrosion and erosion prevention, based on geographic location.
Without CPC applied, damage to components occur

If you find corrosion on an aircraft component, you’ll need to follow the OEM’s Standard Practices Manual-Corrosion Inhibiting and Removal Procedures outlined in Chapter
20-04-03-401. Reapplying corrosion prevention compounds contained in the manual helps protect those components.

Be aware that any component needing replacement because of corrosion isn’t covered under the Contractor Logistics Support contract. Corrosion prevention is considered the unit’s responsibility!

So any damage to a component from corrosion is an over and above contract action cost to the government and may be paid by the unit. This increases NMC maintenance time and delays aircraft return to service. 

Over and above includes the component cost, shipping and handling, and any additional processing fees.

So save your unit time and effort by following the proper CPC practices!
