A method for covering an end of a housing for an engine. A cover is positioned relative to the end of the housing for the engine. The cover comprises a structure, a flange comprised of a deformable material extending from the structure around a circumference of the structure, and a retaining feature configured to extend from a middle portion of the structure such that the retaining feature and the flange form a channel configured to receive the end of the housing. The cover is moved in a direction towards the end of the housing for the engine such that the retaining feature extends into an inlet of the engine through an opening of the housing to form an interference fit between the retaining feature and a portion of an interior surface of the housing.

1. A manufacture that comprises: a retaining feature for a cover to an opening of a housing for an engine, the retaining feature configured to extend into an net of the engine through the opening of the housing, the retaining feature and a flange forming a channel configured to receive an end of the housing; and form an interference fit with a portion of an interior surface of the housing;the cover configured to substantially block all airflow into an net of the engine;a secondary retention system for a cover configured to cove an opening of a housing for an engine, such that the secondary retention system comprises a Darkscrew that comprises a manual operation feature connected to a sealing feature connected to a capture feature connected to a contingent retraction feature connected to an engagement feature configured to connect, such that in operation the engagement feature connects to the engine housing and the contingent retraction feature comprises a width greater than a width of the engagement feature. 2. The manufacture of claim 1, further comprising the engagement feature of the Darkscrew configured to conform to, such that in operation the engagement feature engages with, an engagement feature of a hoist receptacle in the engine housing. 3. The manufacture of claim 1, further comprising the manual operation feature being connected to a handle, the cover comprising the handle. 4. The manufacture of claim 1, further comprising the capture feature engaged by a panel connected to the cover. 5. The manufacture of claim 4, further comprising the panel being connected to the cover via being connected to a flange of the cover. 6. The manufacture of claim 5, further comprising: the flange comprising a deformable material configured to extend, such that in operation the flange extends, from around a circumference of a structure;the cover comprising the structure; andthe capture feature of the Darkscrew also being a shearing feature of the Darkscrew. 7. The manufacture of claim 1, further comprising the cover comprising: the retaining feature configured to extend, such that in operation the retaining feature extends, as a hollowed cylinder into the inlet of the engine through the opening of the housing, from a middle portion of a structure; andthe structure, the hollowed cylinder being sealed at one end by the structure, such that the retaining feature and a flange form a channel configured to receive, such that in operation the channel receives, an end of the housing and form an interference fit with a portion of an interior surface of the housing. 8. The manufacture of claim 7, further comprising a holding structure within a hollow portion of the retaining feature. 9. The manufacture of claim 1, further comprising a sealing system configured to block moisture, such that in operation the sealing system blocks moisture, from entering the opening of the housing into the inlet of the engine. 10. The manufacture of claim 9, further comprising the sealing system comprising a group of sealing members. 11. The manufacture of claim 1, further comprising the cover comprising a drain. 12. The manufacture of claim 11, further comprising the drain being located between a sealing system and the retaining feature of the cover. 13. A process of providing a secondary retention feature for a cover for an engine, the process comprising: providing a retaining feature for the cover, the retaining feature comprising a structure and the cover comprising a shape that substantially blocks all air flow into the engine;extending, from a middle portion of the structure, the retaining feature;extending, from around a circumference of the structure, a flange, the flange comprising a deformable material, and the retaining feature and the flange forming a channel;positioning the cover relative to an end of a housing of the engine via the channel receiving an end of the housing of the engine;engaging a Darkscrew in an opening of a panel extending from the flange; andengaging the Darkscrew with an engagement feature of a hoist receptacle in the housing, the engine comprising the housing. 14. The process of claim 13, further comprising placing a desiccant on a holding structure within a hollow portion of the retaining feature, such that an inner surface of the retaining feature forms the hollow portion in the retaining feature. 15. The process of claim 13, wherein an inner surface of the flange and an outer surface of the retaining feature form the channel without contacting an inlet of the engine. 16. The process of claim 13, wherein the structure comprising a shape selected to fully cover the opening of the housing for the engine. 17. The process of claim 13, further comprising the Darkscrew comprising a manual operation feature connected to a sealing feature connected to a capture feature connected to a contingent retraction feature connected to an engagement feature of the Darkscrew configured to connect, such that in operation the engagement feature of the Darkscrew connects, to the engine housing. 18. The process of claim 17, further comprising the capture feature of the Darkscrew also being a shearing feature of the Darkscrew. 19. A process of reducing, relative to a cover, not using a secondary retention system comprising a Darkscrew, for a housing for an engine, at least one of: a material, a weight, a size, and a cost, of the cover for the housing, the cover comprising a shape to substantially block all airflow through the engine; the process comprising: providing the cover comprising: a retaining feature for the cover to an opening of the housing for an engine, the retaining feature configured to extend into an net of the engine through the opening of the housing, the retaining feature and a flange forming a channel configured to receive an end of the housing; and form an interference fit with a portion of an interior surface of the housing, and a secondary retention system comprising: a panel connected to a flange of the cover; andthe Darkscrew comprising a manual operation feature connected to a sealing feature connected to a capture feature connected to a contingent retraction feature connected to an engagement feature, comprising a width narrower than a width of the contingent retraction feature, and configured to connect, such that in operation the engagement feature connects, to the housing. 20. The process of claim 19, further comprising: reducing at least one of: a cost, a time, a material, and equipment required for manufacturing the retaining feature of the cover;positioning the cover relative to an end of the housing for the engine;engaging the Darkscrew in an opening, the panel comprising the opening; andengaging the Darkscrew with an engagement feature of a hoist receptacle in the housing, the engine comprising the housing.
