That's interesting but not about the species of barnacle found on the flaperon: Lepas anatifera (or Pelagic Goose Barnacle).

Habitat & Range
The pelagic goose barnacle is not truly an intertidal species: it is found on floating objects in the pelagic (open) ocean, but can found by beachcombers when its host object, such as driftwood and other debris, is washed ashore. This generally causes mass mortality, unless the object is washed back out into the open ocean.This species is found nearly everywhere in the world, though it is more common in tropical and subtropical areas and is unable to reproduce if it drifts into waters that are too cold.
Similar Species
The goose neck barnacle, or goose barnacle (Pollicipes polymerus), may be mistaken for the pelagic goose barnacle only in name as the two species are very distinct. The goose neck barnacle has numerous plates, compared to the two of the goose barnacle.
So there are two very different types of goose barnacles.

Lepas anatifera
Common name(s): Pelagic goosneck barnacle, Pelagic goose barnacle
Description: This gooseneck barnacle ... Attaches to floating objects such as driftwood, glass, or plastic. It has no notch on the side that borders the scutum. The plates are covered with fine striations.
How to Distinguish from Similar Species: Mitella polymerus, the other goosneck barnacle commonly found intertidally, has more than 10 plates in the capitulum and attaches to rocks.
