Solicitation NO: W56HZ-23-Q-L033 Mold/Mildew Restoration Responses to Questions

1. Is mold removal visual external surface only or do you want the electronics opened up and cleaned/mold removal internally as well. I use different mold removing products depending on the surface we are removing mold and decontaminating. I have the ability to remove not only any mold, I can remove and redcoat with new CARC coating as well.

Answer: The Government does not need the electronic internals of boxes cleaned; fabric and metal surfaces are the concern. The contractor must be able to de-panel inspection areas and remove mold corrosion from structural areas as outlined in TM 1-1500-343-23-series manuals.

2. During the remediation process, does each of the aircraft have to be isolated from the others and/or do they have to remain covered or isolated in some sort of containment until all three are completed?

Answer: There is no requirement to isolate the aircraft individually. With prior coordination through Contracting Officer’s Representative (COR) aircraft can be repositioned outside of the current warehouse facility they are located in.

3. Are there other artifacts in the space that are also impacted by mold growth?

Answer: There are other aircraft in the space; however, they are unaffected by mold growth.

4. Is there a nearby exit that can be used to vent when using a negative air machine or air purifier?

Answer: Yes, there is a standard single door and a rolling door that can be opened for use.

5. Is the corrosion on these pieces extensive and does it impact their structural stability? Can you tell me the percent of corrosion on each piece? It appears that the mold is extensive throughout.

Answer: The identified extent of the corrosion does not impact the structural integrity of the aircraft at this time. The corrosion has been identified in crew/cabin areas, nacelles, tail booms, and external panels. We believe the YUH-60 to be the most affected aircraft with identified mold in all visible inspection locations which do not require tools to open or disassemble to gain access. The H-19 and HC-34 are less affected with the majority of identified mold contained to the cabin/crew areas. However, like the YUH-60, no visual inspection which required tools or disassembly of the aircraft was performed.

6. Can the time frame be pushed back into the fall to do the treatment of these pieces? It would help with the heat index in a non-climate-controlled facility.

Answer: Unfortunately, the Period of Performance (PoP) cannot be adjusted due to other mission requirements. Understanding this complicates the service and it is appreciated the increased level of effort required due to this.

7. Can we come see the aircraft in person?

Answer: You are most welcome to come see the aircraft themselves. You would just need to tell Mr. Bryant Macfarlane, bryant.d.macfarlane.civ@army.mil, (334) 255-2521, a date and time when you would be arriving on Fort Novosel.

8. What is the standard to meet that the mold is removed?

Answer: The standard for mold removal is outlined in Chapters 4-6 and Appendix B of TM 1-1500-344-23-2 (attached) with the caveat that in no way is there any requirement to meet airworthiness standards for components. For example, we are not concerned about repair or replacement of fuel line sealants or filters as outlined in Para B-20. We do require that mold corrosion be removed or treated with conversion coatings. However, we do need confirmation from a laboratory, or certified occupational health official, that the post-removal wash effluviant or air sample test demonstrates a concentration of less than 500 spores per cubic meter, includes an outdoor concentration measurement as reference, and includes a raw count ascertained through an accepted methodology (i.e., methods such as bioassay, biochemical assay, culture, direct microscopy, nucleic acid analysis, or immunologic assay) to identify and quantify the specific molds in the sample.

CHAPTER 1

INTRODUCTION

This volume was prepared under the technical cognizance of the Materials Engineering Division, NAVAIR North Island, San Diego, California.

1-1. GENERAL. Military aviation is recognized for its unique and complex set of challenges, including maritime patrol operation requirements and powerful electromagnetic operating fields. The highly constrained maintenance infrastructure available to deployed units to combat corrosion can limit the effectiveness of prevention and corrosion control. The materials used to construct military aircraft also contribute to corrosion.

High strength steels used in landing gear and launch/ recovery systems are sensitive to pitting and stress corrosion cracking, which can lead to catastrophic failure.

Aluminum alloys susceptible to exfoliation and intergranular corrosion are commonly found on wing skin and other load carrying structures. Even magnesium, one of the most corrosion sensitive metals known, is still used in canopy frames and gear boxes.

Added to this is the ever increasing age of military aircraft and the need to comply with stricter environmental regulations. All of these factors combine to make corrosion prevention and control a significant factor in the safe and economic operation of military aircraft.

1-2. PURPOSE. The purpose of this manual is to provide information on materials and procedures to prevent, control, and repair corrosion damage to aircraft on land or at sea.

1-3. SCOPE. The material in this manual contains basic corrosion prevention and corrective maintenance information to be used at Organizational, Intermediate, and Depot levels.

1-4. ARRANGEMENT OF MANUAL.

1-4.1. A complete set of manuals to perform aircraft cleaning and corrosion control functions consists of Volumes I, II, and IV.

1-4.2. ARRANGEMENT OF VOLUME II. Volume II consists of nine chapters and two appendices, arranged as shown in Table 1-1.

1-5. RELATED PUBLICATIONS. Tables 1-2 (Navy) and 1-3 (Army) list technical publications that may be used as supplemental references by personnel involved in cleaning and corrosion control.

1-6. CONSUMABLES AND EQUIPMENT.

Procurement information for ordering consumables and equipment referenced in this volume may be found in Volume IV (Navy and Army) of this manual.

CHAPTER 2

CLEANING

SECTION I. CLEANING AND LUBRICATION

2-1. INTRODUCTION. Cleaning is the first step in preventing aircraft corrosion and wear. Dirt, salt air deposits, and other contaminants can promote rapid corrosion and wear of aircraft surfaces, and can have an adverse impact on aircraft systems performance.

Effective cleaning requires knowledge of the appropriate materials and methods needed to remove these contaminants.

2-2. REASONS FOR CLEANING. Aircraft should be cleaned regularly in order to:

a. Prevent corrosion by removing salt deposits, other corrosive soils, and electrolytes;

b. Maintain visibility through canopies and windows;

c. Allow a thorough inspection for corrosion and corrosion damage;

d. Maintain turbine engine efficiency;

e. Reduce fire hazards by the removal of accumulations of leaking fluids;

f. Improve overall appearance;

g. Ensure aerodynamic efficiency of the aircraft;

and

h. Maintain special paint scheme characteristics.

2-3. FREQUENCY OF CLEANING. All aircraft shall be cleaned according to schedules required by the parent service organization. Navy aircraft shall be cleaned in accordance with the schedule in the aircraft specific manual. In the absence of aircraft specific requirements, Navy aircraft shall be cleaned at least every 7 days when aboard ship and at least every 14 days when ashore. Army requirements are given in Appendix B. Under certain conditions, depending on the type of aircraft and usage, the normal wash cycle may not be sufficient. More frequent cleaning may be required for certain types of aircraft when:

a. Excessive exhaust gases or gun blast soils accumulate within impingement areas;

b. Paint is peeling, flaking, or softening;

c. Fluid leakage (coolant, hydraulic fluid, or oil) occurs; or

d. Exposure to salt spray, salt water, or other corrosive materials occurs.

2-3.1. DAILY CLEANING. When deployed within three miles of salt water or when flown below 3000 feet over salt water, daily cleaning or wipe down is required on all exposed, unpainted surfaces, such as landing gear struts and actuating rods of hydraulic cylinders.

NOTE

Optimum use of taxi-through rinse facilities is recommended for removal of salt contamination and light soils when operating near sea water.

Rinsing does not satisfy aircraft washing requirements, it only removes readily soluble matter from exterior surfaces.

2-3.2. IMMEDIATE CLEANING. Affected areas must be cleaned immediately if:

a. Spilled electrolyte and corrosive deposits are found around battery terminals and battery area;

b. Aircraft are exposed to corrosive fire extinguishing materials;

c. Salt deposits, relief tube waste, or other corrosive contaminants are apparent;

d. Aircraft are exposed to significant amounts of salt water;

e. Fungus growth is apparent; or

f. Chemical, biological, or radiological (CBR) contaminants are detected.

2-3.3. Procedures for decontamination of aircraft exposed to chemical, biological or radiological (CBR) materials are contained in FM 3-5 (Army) or or NAVAIR 00-80T-121(Navy).

2-4. WATER QUALITY. Cleanliness of water can affect aircraft cleaning operations. Chlorides and pH have the most effect on corrosion. Recommended guidelines for

2-2 the quality of fresh water used for cleaning and rinsing are shown in Table 2-1. The limits for chlorides and pH shown are approximately the same as for potable water.

Adequate disinfection should be provided to control the growth of microorganisms in the water.

CAUTION

Authorized cleaning agents are listed in this chapter and Volume IV. Do not use unauthorized cleaners. Although commercial cleaners may appear to perform as well or better than approved products, these materials may be corrosive to aircraft alloys.

2-5. CLEANING COMPOUNDS. Cleaning compounds work by dissolving soluble soils, emulsifying oily soils, and suspending solid soils. There are several types of cleaning compounds, each of which clean by one or more of these mechanisms. The following paragraphs describe the various authorized cleaning materials for aircraft surfaces. Paragraph 2-9 provides detailed cleaning procedures.

2-5.1. DILUTION. MIL-PRF-85570 Types I and II, MIL-PRF-85704 Types I, II and III, and MIL-D-16791 detergent cleaning compounds should be diluted with water as specified prior to use. Other detergent cleaning compounds may also require dilution with water. In general, more concentrated solutions than those recommended do not clean better and are wasteful;

MORE IS NOT ALWAYS BETTER. In fact, higher concentrations can interfere with effective cleaning and rinsing processes. The solution merely becomes slippery, prevents the washing pad from loosening the soil and makes rinsing more difficult. Do not exceed the recommended dilution.

High strength steels (typically 180 ksi and above), some high strength aluminums, and some stainless steels can develop a condition…
