About 30 years ago, as holder of an RPPL, I was told that after signing the MR I should add (self only) which presumably meant that I could fly the plane but that the next guy would have to sign his/her own MR.
Does anyone know if this had any legal status then or if it might have legal status now? It might be wise to add (self only) if you have doubts about whether you are legally entitled to sign an MR.
